This week, New Orleans-based singer-songwriter and ace guitar player Lindsey Baker, who records and performs under the name Guts Club, will play Lowcountry with some killer local support. Guts Club, on tour behind Trench Foot, a breakthrough of a third LP that hit last July, boasts a moody, swampy, folk and rock-based sound (with some alt-country feels) that ranges from warbling acoustic meditations to more polished, electric forays — all displaying Baker’s ever-budding prowess as a songwriter. Dig her music at gutsclub.bandcamp.com. Also on the bill are roots/soul/country rock firebrand D.T. Buffkin, who released his finest work to date last year in Saturday Night, Sunday Morning, and the ever-enthralling Lonely Horse, a high emotion desert blues/rock duo and one of SA’s most cherished original acts over the past several years.
