Last night at Boston’s STS9 late night party at Bill’s Bar, a packed crowd was treated to sets by Psylab as well as headliners The Glitch Mob. The evening took an interesting turn when the Glitch Mob brought out the evening’s very special guest Bassnectar. After sharing the stage for a stealth performance as GlitchNectar with The Glitch Mob’s Ooah, Bassnectar proceeded to close the night out with a 45 minute solo set. This Saturday Bassnectar and The Glitch Mob will again perform with Sub Swara and DJK at Club Rebel for STS9’s official after party. Perhaps Boston’s stealth collaboration will inspire another GlitchNectar set tomorrow.
