I liked Flux, although their second attempt at a electro-dance track 'Mercury' was a disaster, so it will be interesting to hear it, let's put it that way.
Flux > Mercury > One More Chance. I love Mercury. Fantastic mess as someone said!
I don't like the piano intro at all, makes it sound a bit eurotrash, but the track gets better. Definitely still has that Bloc Party vibe, but they're changing it up and that's cool. Certainly not as good as their previous material.
