Renowned for the intricate scrap metal constructions-cum-musical instruments by which they soundtracked some seriously intense pre-millenial anxiety, apocalyptic art-punk group Neptune has re-emerged from Boston’s junkyards with a fresh batch of abused electronic gadgets and a totally new sound. Adding to their trademark panicked noise and junkyard clangor, the group’s newfound love of skittering electronics and mangled circuitry places them squarely amid the spazzed out electro-punk scene. Live, Neptune gleefully tears at sound, bouncing around the stage in an anxious pitter-patter of explosive electro-noise, with instruments named such things as “oscillator organ,” “electric thumb piano,” “tupperphone,” “electric floor tom,” “telegraph noise box,” and “electric gas pipe.” This is truly a spectacle that has to be seen to be believed, so catch it at Soundlab on Thursday (Aug. 17), 9pm.
