He seems to only have one piece of music available, Rumble And Sway, an EP ("extended play") from 2013.

The record is pretty darn good, but as of this writing (early October, 2015), there's no follow-up. A couple of guest appearances with Eminem and X Ambassadors, but no full length from the man himself.
Maybe if my legion of followers starts calling their local radio stations, we can change this.
Here is one sixth of the album, Have A Little Faith.
....and here's an acoustic version
The rest is in the Vault.
