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.
