Two Guided By Voices shows – here’s what I know for sure one is from the Khyber – the second is from New York.
The dates I have on the tape are June 23rd 1994 for Khyber and June 24, 1994 for New York. According to the GBV database and this flyer the New York show was on June 24th. According to Marc (thanks for the song titles as well): second NYC on is def Threadwaxing 1994.06.24: there is a Threadwaxing comp that features ‘Scientist’ and it’s the same version as he gives a little verbal intro that matches.
If you haven’t picked it up yet – go buy the New GBV album.
