Mumblr recently returned from an extensive journey around the U.S. that they dubbed the Family Fun Tour. They also recently shared a collection of recordings, accumulated over the last three years and now titled Foster Kids: B-sides and Unreleased Songs. The Philly quartet will be donating all proceeds from the seventeen-song album to Planned Parenthood so be as generous as you can and grab your copy below. Mumblr is scheduled to perform next in Philly on Thursday, January 26 at Johnny Brenda’s, but you never know if the guys will pop up for a performance somewhere around town before then so keep a lookout.
