I sense adults behind the scene. I can see the singers 14 though, but that might just be the fact that I'm English? Dunno. They're from laahndaahn taaaahn, right? Sounds like something else I can't put my finger on.
Also, I started writing music when I was 15 and put out my first demo when I was 16. It ain't THAT impressive.
Thought to be fair my early stuff was pretty shit.
EDIT: The Smiths?
EDIT EDIT: From a Guardian article about them I looked up because I was bored: 'Alice Costelloe, 14, the Johnny Marr-worshipping guitarist'. AH HA. Also, now I think about it, I've seen bands this young before myself, playing original material. My sisters band are all under 14, though they are dangerously shit, never practice and have written I think only one song, and I once saw a fairly decent punk band who were all 15 and under.
