The Revelers have it figured out: Drop vinyl-only, four-song EPs (Volume 2 includes a complimentary CD containing all eight tracks from both volumes) in between full-length releases to stimulate and maintain fan interest. But technically, “Classics,” as part of the title, doesn’t mean a regurgitation of familiar favorites. Only Warren Storm’s “Nobody Would Know” fits that concept, but loosely so since the ’68 original version skirted piano-fueled country lines. In the capable hands of the Revelers, it mutates into something beautiful falling between swamp pop and jazz, especially given drummer Glenn Fields’ expressive style of singing and guitarist Chas Justus’ eloquent late night licks.

More importantly, the Revelers reinvigorate swamp pop by smartly identifying songs that can be adapted into its format. “A Trip to the Moon” is just as spirited as the Gary U.S. Bonds original but is beefed up by the group clapping hands and shouting the rocket countdown in the middle. Blake Miller capably captures the dreaminess of Arthur Alexander’s “If It’s Really Got to Be This Way” with a sauntering tempo that stays true to its predecessor.

Of the four tunes, Spooner Oldham’s “Lonely Women Make Good Lovers” is the best example of an otherwise unimaginable adaptation. Often covered by country artists, the Doug Sahm–inspired arrangement of “Lonely Women” is pepped up by Miller’s Tex-Mex accordion gliding and Chris Miller’s attacking sax lines. When it comes to swamp pop, the Revelers make it look like an old dog that learns new tricks.
