Bloc Party are really good, Silent Alarm is probaly in my top 5 of the year so far. They really don't sound anything like the strokes or franz ferdinand, they're alot better musicians (not that, that automatically makes it better music). The drumming in the album is fucking fantastic and the bass works really well with it. The guitar playing is really good and quite inventive at times, the two guitar players work really well together and create a very different sound to the likes of the strokes who always seem to really on repetitive downstokres of power chords (i do like the strokes though). Overall their sound is a lot darker than franz ferdinand although they do both have that danceble rock sort of sound, but franz ferdinand is a lot poppier. Kaiser chiefs are quite catchy but a bit annoying.
