The Preservation Hall Jazz Band have been playing music for 50 years, but their first album of entirely original material will finally be released next month. You can hear "Rattlin' Bones" off of That's It! right now though, so check it out and feel the New Orleans vibe wash over you.
Also, go to Paste to see a video in which the band talks about making the song.
You'll be able to get That's It! on iTunes on July 9.
