It's still amazing to me that Creedence Clearwater Revival, a late-60s, early -70s Bay Area band, was so good at playing Louisiana swamp blues; but they were. And John Fogerty, the band's controlling but visionary leader, was largely the reason why (proof below).
The album might as well be called "What's Done is Done. Let's Rock." There's an air of openness and self-awareness to album; sort of a second (or third) wind for Fogerty. Songs range from simple blues/country ("Don't You Wish It Was True") to reflective nods to the old days ("Creedence Song") to straight-up political rock and roll ("I Can't Take It No More").
