In April, it was quite clear that Foo Fighters were hard at work on their eighth album. Butch Vig let slip they were about halfway done on the next one, and toward the end of the month we saw some photos of the gang in action out in Joshua Tree, California. But then came May. And instead of wrapping up this much anticipated new long-player, Dave Grohl and co. are back to screwing around, surprising fans with lengthy and/or intimate secret shows in random-ish cities. The nerve.

On Monday night, the Foos did a surprise two-hour set at Washington D.C.’s 9:30 Club (where that thing happened with the Jäger shot on the bar). And on Wednesday night, it turns out, Grohl popped up in Nashville, Tennessee, to regale an unsuspecting audience with an hour-long solo set that found him playing his band’s hits on an acoustic guitar to fewer than 100 people. While no video has yet emerged, The Tennessean was thankfully on hand to record the event with their words.

“My name’s Dave Grohl. I’m a drummer,” he reportedly said at the start of his set at The Bluebird Cafe. He evidently opened with “Times LIke These” before playing “Big Me,” “Friend of a Friend,” “My Hero,” “Skin and Bones,” “Wheels,” “Learn to Fly,” “Ballad of the Beaconsfield Miners” and “Everlong.” There was a camera crew on hand to capture the entire performance, so expect to relive the night at some point in the not-too-distant future. Still, no new songs, so … blerg.

But, remember how freaking good and real “Everlong” sounds acoustic?
