Dennen's wunderkind rise has been impressive. In 2004 Dennen released his self-titled debut, followed quickly by his sophomore LP "So Much More" (2006,) which spent months on the Billboard Heatseeker chart. The release drew the attention of John Mayer, for whom Dennen opened in 2006 and 2007. In 2008 the artist released his follow-up, "Hope for the Hopeless", which debuted at #41 on the Billboard Top 200 and firmly established Dennen as a definitive new voice in modern songwriting. He's worked with Femi Kuti, Natalie Merchant, and Jason Mraz; he's toured with Dave Matthews, Rodrigo y Gabriela, and The John Butler Trio; and he's played Bonarroo, Austin City Limits, Coachella, Outside Lands, and Newport Folk Festival. He's also become the go-to guy for some of the best and most artfully soundtracked contemporary TV shows. His songs have appeared on "Scrubs", "Grey's Anatomy", "Parenthood", "Brothers & Sisters", and "House" among others.
