Peter Frampton may very well be one of the most underrated guitar players in the rock idiom. He began his career as the lead singer of a one-hit pop band called the Herd, but proved his instrumental chops in Humble Pie before he became one of the most in-demand session guitarists in rock music.

His early solo albums were critically acclaimed, but after the record-shattering success of 'Frampton Comes Alive!' he made a key error by posing shirtless for the cover of Rolling Stone. His commercial fortunes slipped thereafter, but Frampton got the last laugh -- shirt firmly in place, he won a Grammy in 2007 for his all-instrumental album 'Fingerprints.'
