Geoff Calhoun joins Keith as they talk with Matt Mahaffey, the frontman and visionary behind the band sElf... and so much more. Oh, trust us, you know Matt's work. 
Matt Mahaffey grew up in Kingsport, Tennessee, and started writing songs and playing the drums at age 4. He would often perform with his brother, Mike Mahaffey when they were growing up. 
By age eleven, he played drums at Dollywood in Pigeon Forge. In the mid-nineties, he moved to Murfreesboro, Tennessee, and attended MTSU. He lived and worked for ten years in Murfreesboro, where he co-founded Spongebath Records and formed the band sElf in 1994. 
In the early 2000s, Mahaffey relocated to Los Angeles. 
Matt has performed with and produced artists like Pink, Beck, Liz Phair, Tenacious D, Snoop Dogg, Beyoncé, Keith Urban, and on and on and on. He has also worked with various filmmakers, including Ivan Reitman, Michael Mann, Jeffrey Katzenberg, Andrew Adamson, & Hans Zimmer (for film score). 
He's also written jingles and composed music for Pedigree, Jumbone, Medicare, and Lexus. His music has been featured on numerous shows, including CSI: Miami, DanceLife, Entourage, MTV, E! Entertainment, Dirty Sexy Money, Weeds, and 60 Minutes.
You get the idea. 
He's done a lot.
