Bloc Party will be premiering their brand new song “Flux” on NBC’s Late Night with Conan O’Brien TONIGHT (Thursday). For those of you without DVRs, “Flux” will also be available on a new, improved digital re-release A Weekend in the City, as well as via a Flux digital EP, both of which will be released to all digital service providers by Vice Records on November 20th. The EP features the original version of “Flux,” recorded recently with A Weekend in the City’s producer Jacknife Lee, as well as special bonus tracks to be confirmed.
