Any Bloc-heads out there were probably as thrown for a loop as I was when they first heard Bloc Party's one-off single, Flux. Not sure if it grew as quickly on all of you as it did on me, but count me as one of the converted. I would definitely be down for some pantless dancing to tunes like that. But here, Flux gets a jazz-lounge make over, complete with acoustic plucking, light drumming, and airy female vocals. Check it.
