Instead, the laid-back Dennen feels most at home surrounded by nature and making music that exudes an earthy appeal with easy, breezy, feel-good sounds.
Dennen isn't committed to just one genre, however: His music ranges from blues, rock and folk to reggae and funk.
He stopped by The Early Show's "Second Cup Café" Saturday to perform his hit single, "Make You Crazy," off of his latest album, "Hope for the Hopeless," as well as "The One Who Loves You the Most," off his 2006 album, "So Much More," to mark the day of love, Valentine's Day.
Dennen's early 20s were surrounded by the sheer beauty of Yosemite, Calif., as a camp counselor leading often-troubled teens on backpacking trips through the Sierra Nevada mountains. Showing them how to live off the land gave Dennen a great appreciation for the simple things in life.
"Hope for the Hopeless" was released in October 2008 and debuted as the No. 4 Independent Album, the No. 6 Digital Album, and entered at No. 41 on the Billboard Top 200 Chart.
John Mayer is said to be one of Dennen's biggest fans, according to Rolling Stone magazine, which dubbed him "Artist to Watch" in 2007 after his 2006 release of "So Much More."
Dennen's songs have been featured in episodes of "Grey's Anatomy," "Scrubs" and "House." He will join fellow musicians, The Fray, who've also received a lot of love from "Grey's Anatomy," overseas, performing in the U.K.
The music doesn't stop there. Dennen will be joining music legends Bruce Springsteen & the E Street Band, Phish, Wilco, and the Beastie Boys at the 2009 Bonnaroo Arts & Music Festival in Manchester, Tenn., the weekend of June 11-14.
