The all-day Southern Solstice Revival at the Pour House this weekend might sound like a pagan keg party where rowdy locals start dancing around like maniacs, praying to the Southern sun gods, but it’s actually an all-day showcase featuring performances by some of Charleston’s most colorful blues, rock, and Americana acts. Featured acts include Gaslight Street with a guest horn section, the Broadcast (from Asheville, N.C.), Hit or Miss (featuring members of Sol Driven Train), Jordan Igoe, Aaron Firetag, the V-Tones, Skye Paige, and others. Local blues/country/swing combo Whiskey Diablo (pictured) will celebrate the release of their jazzy debut album, Wail & Serenade, with a late-night set on the main stage. Singer/guitarist Patrick Blake and his core bandmates — drummer Brian Widlowski and bassist/banjo player Jonathan Gray — recorded the 12-song collection at Jay Miley Studios in Charleston. “The album has touches of blues, jazz, and country,” Blake says. “At times, it is a booze-soaked circus falling off a cliff to certain death, and other times, it’s gentle, complex, and soft.” Blake and his band will welcome guests on stage, including guitarist Bobby Hogg, pianist Whitt Algar, and sax player Keith Namm. Holy City Brewing, Cathead Vodka, and Virgil Kaine Bourbon are sponsoring the show. Music on the deck starts at 3 p.m.
