i don't really mean established bands here, but feel free to link to u2's myspace page if you really want to.
anyway, which bands on myspace do you really like? we haven't had one of these threads for a while, so i'll go first with.
johnny horizontal- www.myspace.com/johnnyhorizontal
nice swirly post-rock stuff, and they manage to not fall into the trap of being an explosions in the sky/mogwai clone. which is good.
the octopus project- www.myspace.com/theoctopusproject
fun and lovely and fuzzy instrumental electro-pop type stuff. YUM!
they have obvious influences, but i really like them. their samples are quite emo too :D
