15. Nils Lofgren, 'Face the Music'
This singer-guitarist has been hiding in plain sight, as a solo artist and bandleader in his own right, for nearly 30 years as a member of Bruce Springsteen's E Street Band. Face the Music pulls Lofgren's own twist on rock & roll fundamentals and songwriting-outlaw romanticism forward, at length, on nine CDs (plus a DVD), starting with his crackling precocity in the trio Grin and the gripping Stones-y noir of 1975's Nils Lofgren and the next year's Cry Tough. The many, previously unreleased tracks includes this surprise: a Grin demo of that '75 album's brawling plea for a Stone's good health, "Keith, Don't Go," with Lofgren's friend and other frequent employer Neil Young on helping vocals.
