Omg, that Steven Wilson's one is awesome.
I don't use to like hardcore metal or even metal and maybe warheart's idea of rock it's a bit different from mine,(I consider rock groups like The Strokes, Mando diao, REM, Silvertide, Artick Monkeys, etc). I don't know if there's another thread like this for any type of music, but if there's not, i think the chances for creativity inspiration are highly reduced. Anyway, since Emong linked some shoegaze videos, i feel a bit free to post alternative rock and it's relatives.
