Fluke has been around forever, and has been one of my favorite groups since about the mid 90's
They've had thier music in everything from commercials, to video games, on tv, high up on charts overseas, but they don't really seem to have a huge following that I know of.
Anyways, I'm not entirely sure how easy or difficult it would be for you to check them out, but I HIGHLY reccoment thier album "Risotto"
favorite song on there is "Kitten Moon"
oh, yeah, btw, they are electronic artists, but they have a very wide variance in thier music.
