This 2008 collection of “Outlaw Country” features everyone from its founders, Waylon Jennings and Willie Nelson, to Southern Rockers such as the Allman Brothers, Lynyrd Skynyrd, the Marshall Tucker Band and Molly Hatchet, and even Waylon’s son, Shooter Jennings, who’s emerging as an alt-country star, and mainstream traditionalist Gretchen Wilson. At this juncture thirty years since Willie and Waylon turned off the Nashville assembly line and refused its tendency towards ‘pop’ sweetenings such as strings and excessive backing vocals, “Outlaw Country” has become a genre more defined by the characters making the music than an actual sound. Roughly defined it’s tough guitars, real fiddles, barroom pianos, and driving beats that stake their territory in these well-known favorites, from the Allmans’ “Ramblin’ Man” and Johnny Paycheck’s “Take This Job and Shove It” to Nelson’s “Whiskey River” and Johnny Cash’s live take on “Cocaine Blues.” David Allan Coe made a career of being an un-PC, unrepentant dirty talker. Only Tanya Tucker and Travis Tritt seem ill-cast.
