Here’s something that doesn’t turn up often, nearly 30 minutes of vintage live concert footage of renegade psychedelic folkies, The Holy Modal Rounders:

A live concert in the Vondelpark in Amsterdam in the Summer of 1972. Shot by Videoheads who also organized the concert. The Holy Modal Rounders appeared frequently wherever the Grateful Dead were appearing. Electronically colorized using the Marcel Dupouy colorizer accesory for the Movicolor Video Synthesizer.

Courtesy of the fine folks at Videoheads, the same Dutch outfit who recently posted that amazing live footage of Mick Farren and the Deviants from 1969 on YouTube
 

 
Below, the trailer for the 2007 documentary on the Holy Modal Rounders, Bound to Lose.
