The opening "Ramble Tamble" is bookended with a basic Creedence tune, but the middle five minutes become a hypnotic instrumental with an air of finality, a giant leap from the meandering jams that made up the band's 1968 eponymous debut. "Up Around the Bend" is an excellent rocker, while "Travelin' Band" has a 50s feel and "Who'll Stop the Rain" is the band's best slow song, an coustic ballad with poignant lyrics and double-tracked vocals that lend a haunting effect to the chorus.

Much of the album is covers, although CCR's unique sound makes them sound like originals. "Ooby Dooby" and "My Baby Left Me" are just fun, "Before You Accuse Me" is a standard take on the tune that is still pleasant, and "I Heard It Through The Grapevine" is faithful to the original, with one caveat -- it's 11 minutes long, filled with riffing and tons of solos.

This leaves "Lookin' Out My Back Door," a pleasant drug song; the poignant closer "Long As I Can See The Light," featuring some excellent Fogerty vocals; and "Run Through The Jungle," a cousin to "Born on the Bayou" in that it retains all of that song's swampy murk and menace ("They told me don't go walkin' slow / Devil's on the loose / Better run through the jungle / Whoa don't look back to see").

Cosmo's Factory is the apex of Creedence's career, pulling all their strengths together in one massive burst of creativity.
