Watch your wallet when Potatohead People come around: The Montreal duo go deep in the pocket. Their woozy funk is rooted in the slap bass and neon keys of early-‘80s bands like Pleasure; their acoustic textures lead back to obscure ‘70s soul cats like Matthew Larkin Cassell. And they share affinities with a host of contemporary throwback acts—Teddy Mike, The Pendletons, Sixtus Preiss—who deal in lurching boom-bap beats and retro homage.
