At the end of October, Foo Fighters launched a mysterious countdown clock on their website. Now, the countdown is over, and we know what the deal is: Foo Fighters have just released a new EP called Saint Cecilia, recorded live in Austin’s Hotel Saint Cecilia while the band were in town to headline Austin City Limits. Ben Kweller, Gary Clark Jr., and the Preservation Hall Jazz Band are all featured on the EP. Foo Fighters are offering it as a free download — which includes a lengthy note and a description of the recording sessions from Dave Grohl — so you can pick it up here or stream it below.
