Rock ’n’ roll comes in many different shapes and sizes. Some of the latest interpretations and reinventions of the genre will be on display Saturday, Oct. 18, for Instant Pleasure Fest at the Broadberry. Headlining the bill is the fluid country psychedelia of Atlanta’s Futurebirds. Their fuzzed-out Ken Kesey take on the Flying Burrito Brothers forsakes frivolous flights of fancy in the same way the much-hyped Avers apply a refreshing restraint to their respective reverb-soaked shoe gazes. Roanoke’s the Young Sinclairs go for a more straight-ahead, late-period Everly Brothers meets the 13th Floor Elevators with their yesterday-is-today offerings. Rounding out the bill are Richmond psych-rockers the Diamond Center, the debut of Chrissie Griffith’s new art rock trio Lady God, Dave Watkins’ solo guitar freak outs and the mix-mashing sounds of Revolt of the Apes, DJ Harrison and Stimulator Jones in-between sets. The night of psychotropic indulgences begins 8 p.m. Admission is $15. thebroadberry.com.
