Pilam erupts with its thunderous Human BBQ for its unprecedented 36th year today, and the music frathouse features a stacked lineup of 18 bands playing its basement and 1st floor. The event will be headlined by Brooklyn buzz band Total Slacker, and will feature other noteworthy out of towners like NYC’s Total Slant and Betlehem’s indie duo Slingshot Dakota. But Philly will be very well represented by the like of Cold Fronts, who should be seeing big things coming their way after recently signing to Sire Records. The ongoing psych rock project of booking wizard Andy Molholt, Laser Background will bring their synths stylings to the party. Mumblr will bring the fast paced fuzz punk, and Secret Plot to Destroy the Entire Universe will bring their hard-hitting, emotive anthems. Add in 11 more bands of varying style, plenty of meat and veggie BBQ options, and the Human BBQ’s tendency for delivering surprise performers; and you have a stacked day of music.
