I've been a fan of Charlie Worsham's for a few years now. A music blogger turned me on to his 24-hour cover challenges and I must say, they are awesome!
Here's how it happens: Charlie takes suggestions for covers through Twitter , Facebook , and more. He will then choose a song to cover, and perform the entire thing by himself, every instrument and vocal, in less than 24 hours.
Sounds tough right? Check out this playlist and his latest cover challenge.
