From Piper, we have a 1976 performance of "Eulogy for B.M." recorded at the Artpark in Lewiston.
Here is the first post: Two Zappa pieces performed by Toad in 1973. They were recorded in a high school gym, transferred to a cassette, and then copied onto another cassette which then sat in a box in my closet for 43 years. Lo-fi at its lowest? Perhaps, but it may be all we have of Toad. If any of the Toad-guys would like to submit more detailed program notes, I'll post them.
