10. Neil Young and Crazy Horse, 'Psychedelic Pill'
Appearing alongside his memoir and the history-lesson covers set Americana, this is as inspiringly strange as anything he's done. It opens with the 27-minute "Driftin' Back," a free-associating timeline that morphs from coffeehouse folk to charred Crazy Horse jam. Feedback and flashbacks, sentimental and not, flow between inspired moments of old-coot humor ("Gonna get me a hip-hop haircut!"), all peaking with the 16-minute "Walk Like a Giant," a doo-wop noise-metal Sixties lament that goes out stomping. Like a giant, indeed.
