Sitting in a cramped rehearsal space in London, the air thick with the smell of ozone and over-caffeinated energy, you do not expect to meet a 14-year-old who possesses the vocal grit of a seasoned road warrior. But Bella Rosa is exactly that. She isn't your average teenager navigating the awkward social hierarchies of high school.
For Rosa, music isn't a hobby or a phase. It is a biological imperative. While her peers are likely obsessing over social media trends or upcoming exams, she is fronting an eponymously named hard rock outfit that sounds like it was forged in the same furnace as the greats of the late 90s.
The band has been riding a wave of momentum since Dec. 15 of last year. Their debut single, Out of Breath, has already cleared 30,000 streams on Spotify. In an era where the algorithm usually buries independent rock, those numbers are a loud, distorted wake-up call to the industry.
The lineup behind her provides a technical backbone that most teen projects lack. You have lead guitarist and musical director Santiago Izaciga and drummer Andy Gomez, both bringing a specific Bogotá, Colombia intensity to the kit and fretboard. Then there is bassist David Goodman, a Barbados native who rounds out this oddly global, London-based quartet.
It is a strange mix on paper. But on stage, or even just sitting across from Rosa in a socially distanced interview setup, the chemistry is obvious. They recently returned to rehearsals after the COVID-19 lockdowns put a temporary muzzle on their output.
We sat down with the young frontwoman to dissect her obsession with heavy riffs and her plans for the future. I asked her how this all started, and what exactly drives a kid to skip the pop charts for the rock charts.
Rosa says, "Since I was very young, my dad was always in a band and they would practice in our basement. I would watch them play and I just loved what they did. When I was about 11 or 12, I told my dad I want to be musician — I wanted to do what he did, because I want to be able to change the world for the better through music. Because in my eyes, our world isn’t exactly the best at the moment. So, my whole goal and why I started was because I wanted to help it change."
It is an ambitious goal. Most 12-year-olds want to change their curfew, not the world. But there is a sincerity in her voice that makes you believe she might actually pull it off.
Her entry point into performance was surprisingly dainty. She started on the ukulele, an instrument usually reserved for indie-folk covers and campfire singalongs. It is a far cry from the Marshall stacks she uses now.
She says, "Well that all started because of a musician named Grace VanderWaal. She won America’s Got Talent back in 2016, playing the ukulele and singing when she was just 12 years old, which was a few years older than me at the time, but I really loved her music. So, I told my dad I needed a ukulele and I was going to teach myself, and I did. I taught myself ukulele and I picked it up pretty easily. After that, I started writing but with guitar, drums, and bass. I still haven’t learned the bass, but I’m down with guitar and drums."
Picking up three instruments before your voice even fully matures is a flex. And it highlights a technical curiosity that serves her well in a genre that demands more than just a pretty face and a preset beat.
But the pivot from VanderWaal’s sunny, pop-adjacent folk to the darker hues of hard rock is a significant creative leap. It is the difference between a summer breeze and a thunderstorm.
I just didn’t like the idea of everything always being happy. ...I realized life isn’t just sunshine and rainbows. There’s a lot of hard stuff too, like growing up, and I wanted to write about that.
Rosa says, "In the beginning, I really wanted to do pop music. But, after a while — and I know this sounds weird — I just didn’t like the idea of everything always being happy. I watched a lot of interviews of celebrities and singers and actresses and they would say that through their craft, they wanted to show people that life isn’t always positive; you also have to talk about the hard stuff — you have to be truthful. So, I feel like hearing that and getting to be an age where I was a teenager, I realized life isn’t just sunshine and rainbows. There’s a lot of hard stuff too, like growing up, and I wanted to write about that."
This is where the real value of her work kicks in. Most teen stars are coached to stay in the "sunshine" lane because it sells. Rosa’s rejection of that artifice is her strongest asset. Truth in rock is a currency that never devalues.
Writing that truth often involves her father, Gerry Rozo. It is a collaborative effort that bridges the generational gap through distortion pedals and shared melodies.
She says, "We would sit in our little studio area, and he’d bring out his guitar and we would just talk about whatever I was going through or what I wanted to write about. Then we would come up with the right words, and I would let him know how I wanted the melody to sound, because I didn’t know how to play guitar that well at that point and I didn’t know how to put like chords together. Sometimes I would hum it, and he would add the chords and it would actually sound really good. It could get a little stressful at times because there’s still that father/daughter dynamic — but even then, we’d always make a really good song out of it."
That stress is likely where the edge comes from. You can hear the friction in the tracks. It isn't over-polished. It feels lived-in.
When Out of Breath dropped, the reaction was immediate. For a debut from a local London act, the numbers were staggering. It wasn't just friends and family clicking play.
Rosa says, "It was the first song we put out, so I never thought we would reach so many people, and I was fine with that. Then one day I woke up and was getting ready for school and since my dad would check the streams every morning, he noticed it increasing a lot. Once it reached 20,000, it was insane, and my heart skipped a beat. It was crazy, but good crazy. My biggest worry was that people weren’t going like it and I know that you can’t really worry about that when you’re in this business because not everyone is always going to be behind what you do. But the response literally just blew me away."
The song itself has a frantic, claustrophobic energy. It makes sense when you hear the origin story. It wasn't born from a heartbreak or a generic trope. It was born from a literal lack of oxygen.
She says, "It actually came from an experience scuba diving. I had to do this test, and I had the worst anxiety because at one point I had to take off the breathing apparatus underwater and it was terrifying. I didn’t want to drown, and when I got out of the water, I was crying. After a minute I just stopped, looked at my dad and I said — the next song we write is going to be called Out of Breath."
That kind of visceral inspiration is rare. Most writers try to manufacture drama. Rosa just went underwater and found it.
There is also the issue of optics. In the music industry, age is often used as a gimmick or a barrier. Rosa has to navigate both.
She says, "Some people will see pictures and think I’m older than I am. Some have even thought I was in my 20s because I’m wearing a bunch of makeup, or because of the way I dress. A lot of people don’t believe me when I tell them because of the kind of music we play. One of my biggest worries has been that I wouldn’t be taken seriously, or I wouldn’t get respect because of my age, but honestly, I see it as an advantage as well. I learned very quickly that being so young and having the kind of voice I have —I shock people, and sometimes that’s a good thing."
And she does shock. Her vocal range has a maturity that betrays her birth certificate. It is a classic rock growl wrapped in a Gen Z package.
This maturity isn't just vocal; it is mental. The industry is a meat grinder for young talent. If you do not have a thick skin, you get chewed up before the first tour ends.
Rosa says, "I had to mature really quickly because of this, and I love it. I love the person who I’ve become, and music has gotten me through a lot and has taught me so much. All the people that try to tear me down because of it I say go for it — hit me with your best shot. Honestly, I just have to deal with it and push through it. It all drives me to be better."
The next step is Roller Coaster. It is a track that has been sitting in the vault since Jan. 15, waiting for the world to open back up.
She says, "As soon as possible! It was recorded back in January, and we’re in the middle of mixing it because we want it to be perfect. COVID slowed everything down, but we’re exciting to get everything back on track. The idea for this one came from talking about that point in everyone’s life where you’re going insane and your emotions can move from being really high to being really low quickly. It’s like a roller coaster. Life and your mental health and everything else. No one’s always happy, you always have your ups and downs. It’s also a song I didn’t write with my dad, but with the band. That was always the goal, to have us all be a part of the music, so the guys wrote the music and I wrote the lyrics. I really hope people like it because it’s an amazing track."
Moving from writing with her father to writing with the full band — Santiago, Andy and David — is a crucial evolution. It marks the transition from a "project" to a legitimate unit.
Final word from the frontwoman? It is about the grind. There are no shortcuts in this theatre of noise.
She says, "I think the biggest thing I’ve learned is to be a successful musician, you have to work with really professional people. I’ve also learned through this whole journey so far that you need to work hard, you can’t just sit at home doing nothing all day and expect to be perfect and have all these people supporting you out of nowhere, because that doesn’t happen. You also need to surround yourself with the right people, and that’s the message I want to send out."
If Roller Coaster hits with the same force as Out of Breath, London might have a genuine rock star on its hands before she can even legally drive the tour van.
