Local psych rockers Gondola are bringing their explosive brand of blues rock to Johnny Brenda’s tonight. The power trio’s sound is a pummeling mix of driving drums, heavy basslines, and deafening guitar riffs reminiscent of sludgy 70s Black Sabbath metal. Rounding out the evening’s bill are fellow heavy psych rockers Serpent Throne and Baltimore’s The Pilgrim. Johnny Brenda’s, 1201 N. Frankford Ave., $8, 8 pm, 21+ – Dan Brightcliffe
