In 1989, New York City’s Boss Hog introduced the world to a blues-punk sound they called “pig fuck.” After a solid decade of rocking out, they went into a lengthy hiatus. But, in 2016, fans were likely as happy as swine in shit to hear that new music was on its way. Though last year’s Brood Star EP was written before the most recent U.S. presidential election, singer Cristina Martinez told the website Essentially Pop that its defiant songs have become “more resonant” since then. She and her husband/bandmate, Jon Spencer — of the Jon Spencer Blues Explosion — also contributed a track to the anti-Trump benefit compilation Battle Hymns. Catch Boss Hog on Sunday, May 21, at the Higher Ground Showcase Lounge in South Burlington. Locals Aspero Saicos open.
