It's pretty remarkable that this Bay Area crew had never even visited the South until they tasted fame. This 1969 album is an ode to Southern roots music that touches on a diverse array, from country-gospel ("Cotton Fields") and rockabilly ("It Came Out of the Sky") to New Orleans blues-funk (the title track) and street corner shuffle ("Feelin' Blue"). The corking "Fortunate Son," one of the album's two radio hits, remains one of a handful of Vietnam-era protest tunes to retain bite and relevance today. This largely fun and breezy affair may lack the paranoid edge and blue-eyed soul numbers that mark their best work, but it's easily among the prolific CCR's top three records.
