There is at least one huge difference between Bloc Party and any Emo IMO. Bloc party has one or two songs that are a bit on the whiny side, but just barely, whereas just about all of the mainstream emo that's around these days is all whiny, all the time. Bloc party never sound like petulant children to me. When they moan about something, they come across as actually having something to moan a bit a bout. It seems to be that emo is painting itself into a corner of only singing about frustration. There are so many more emotions than frustration that one could infuse ones music with. I've got the whole Bloc Party album and about 6 other songs and it's their diversity while maintaining a distinctive (while somewhat derivitive, but hey what isn't) sound that impresses me. Props to HoyaSaxa03, great review.
