This is some pretty cool old live footage of ESG. The dancing kiddo is quite good. This video was posted with a couple other videos here. This quote from that post cracked me up:
I only saw them live once, myself — in 1990 or so at a weird hippie warehouse space in Manhattan called Wetlands.
I worked at Wetlands in the mid-1990s so know it pretty well. Mainly though, “weird hippie warehouse space” is a fairly accurate description.
