U.K. rock act Bloc Party will return Feb. 6 with its sophomore Vice/Atlantic album, "A Weekend in the City." First single "The Prayer" will arrive Jan. 29 internationally. The 11-track set is the follow-up to 2005's "Silent Alarm," which debuted at No. 3 on Billboard?s Heatseekers chart.

"One thing that we've learnt from touring over the last two years is that there are other ways to be powerful whilst making music, rather than being completely full on, 100 miles per hour," frontman Kele Okereke told Billboard.com in April. "This next record is hopefully going to be a lot more intricate and layered. We learnt so much about the power of arrangements. I know it sound cheesy, but I guess it is going to be a more grown up Bloc Party."

Two new songs have already been played live: "Waiting for the 7:18," which Okereke wrote after watching his post-college friends lose more and more of their lives to work, and "Hunting for Witches," which was influenced by last summer's terrorists attacks on London's transportation system.

As previously reported, Bloc Party will open for Panic! At The Disco during a fall tour that begins Nov. 7 in Ft. Lauderdale, Fla. A three-week U.K. headlining run will follow, beginning Jan. 27 in Southampton.
