Before there was any such thing as True Blood and the mother of all deep-fried Southern opening credits (hat tip to Jace Everett and his drawling “Bad Things”), there was Wayne “The Train” Hancock. The native Texas musician puts Elvis and Johnny Cash into a rusty bar shaker and gives the whole concoction the old one-two. Hancock makes a stop in Denton to play Friday at Dan’s Silverleaf. The Austin-based musician played to a packed house during 35 Denton, a testament to his surefooted approach to alternative country. His live set is informed by juke joint staples — Western swing, Jimmie Rodgers-style blues and early rock ’n’ roll. And yet Hancock, who sounds decades older than his 48 years, brings on the fire and ire of the rock ’n’ roll he grew up with. If you’re a fan of Hank Williams or Bob Wills, with an occasional craving for something fiercer, Hancock’s gig is for you. Show starts at 9 p.m. at Dan’s, 103 Industrial St. Cover charge is $12.
