Since last fall, NYC has once again had an alternative rock radio station, ALT 92.3, and they are throwing a big holiday show at Brooklyn's Barclays Center on December 6 called "Not So Silent Night." It features Muse, Florence + the Machine, Death Cab For Cutie, Foster The People, Mike Shinoda (of Linkin Park), CHVRCHES, and more. Tickets go on sale Friday (10/19) at 10 AM with an ALT Insider presale starting Wednesday (10/17) at 10 AM.

Florence just brought her headlining tour to Barclays Center (pics)) in support of her great new album High As Hope. Death Cab's tour behind this year's Thank You For Today just hit Brooklyn for two Kings Theatre shows over the weekend (pics coming very soon). Muse's new album Simulation Theory comes out on November 9.
