After leaving Curb Records last year, Hank 3 released a quartet of full-length recordings reminding us that the 39-year-old country singer is an avant-garde conceptualist, just like John Zorn. If Hank Williams Sr. helped invent modern country music, Hank Jr. belongs with Waylon Jennings in the pantheon of traditionalists who turned to outlaw country in the ’70s and ’80s. But neither man would have released a record of crazed speed-metal-flavored musique concrète on the order of Hank 3’s 3 Bar Ranch Cattle Callin’ — one of the four albums I mentioned earlier. “Tim Dowler — Square Bailor” and “Black Cow” feature actual recordings of cattle auctions that are decorated with blasts of distorted guitars and drums. He also continues to record somewhat more conventional country tunes. A proponent of adopting needy animals, Hank 3 hosts tonight’s benefit for the Franklin no-kill animal shelter, Happy Tales Humane.
