254. Grateful Dead, 'Live Dead'
Warner Bros., 1969
After two expensive studio albums put them $100,000 in debt, this live set was more than just cheap, it was pivotal. For the Dead, the magic happened onstage, as demonstrated by the glorious 23-minute jam-outs on "Dark Star" and a raging, 15-minute cover of Bobby Bland's "(Turn On Your) Love Light."
