Did you miss this quote from the singer? "Rock music has predominantly been the terrain of ... There's so much masculine-white-boy energy around it, it makes white males feel good about stuff".
Given Bloc Party's singer is gay your "no balls" criticism is a bit iffy IMO. Are you really saying that all "rock" music must be "ballsy" (whether played by men, women, gay, straight, whoever)?? No room for introspection, contradiction, doubt? plenty of great rock has had that stuff in bucketfuls, just as plenty of great rock is "about" nothing but joy, the moment, excess.
Re Bloc Party, I agree with what Simon R is saying, which goes for the new artrockers in general; where much postpunk was a genuine and often thrilling amalgam of avant
and popular black and white music, the current crop (futureheads, bloc party, franz etc) are at best producing a skilled fascisimile of postpunks best moves rather than a new synthesis. but what would the new synthesis be? can it really be said that "black" music remains almost exclusively "black" or have we moved on? was there more of a
need for a synthesis in the late 70s/early 80s (I'm talking mainly about Britain here I spose), whereas now much music is more organically multicultural anyhow? I work for the Love Music Hate Racism campaign, so these are real live issues for us, particularly when you look back at the effect our predecessor Rock Against Racism had in the late 70s, with RAR's success (or reflection of what was going on anyway?) in putting punk and reggae acts and fans together, arguably helping pave the way for two-tone etc. ( see e.g.
