If, as many contend, Creedence Clearwater Revival was the foremost singles rock band of its time, Cosmo's Factory is the ultimate end-of-the-'60s singles album. Indeed, seven of the album's 11 tracks turn up on Chronicle, CCR's best hits collection. That said, Cosmo's is really a must-own in its entirety. No other album so adeptly laces together the various strands of the CCR sound. John Fogerty's ready-for-AM-radio knack surfaces in "Lookin' Out My Back Door" and "Up Around the Bend." His sober side is in evidence on "Who'll Stop the Rain" and "Long As I Can See the Light." And no white group of its time could cover black music with as much natural flair; check out the 11-minute cover of "I Heard It Through the Grapevine" for proof. The band broke up two albums after the release of this, their apex LP, but Cosmo's Factory cemented CCR's standing as a great American band.
