When I joined KDU Executive Slacks were the biggest band at the station for over 21 (or at least good fake ID) crowd. I was more in the all ages hardcore show faction so although I liked them I never actually got to see them live.
Their bandcamp page has a good description of the band:
They were one of the most groundbreaking bands to emerge out of Philadelphia in the early ‘80s, laying the sonic foundation for future acts such as Ministry, Skinny Puppy, and Nine Inch Nails. Yet the post-punk, proto-industrial sounds of Albert Ganss, Matt Marello, and John Young never earned the significant recognition it deserved.
I’m not sure what year this video was shot but it is from Ripley’s Music Hall so that narrows it down until early to mid 80’s.
Thanks to Flipo from the Excuses for the video.
