Various - Source: Music of the Avant Garde, Issue Number 4 [Source,1968]: liked

The release I listened to and am posting about here contains the following tracks:

Source Record Number One

A. Robert Ashley – “The Wolfman” (15:15)

B. David Behrman – “Wave Train” (15:15)

Source Record Number Two

C. Larry Austin – “Accidents”(16:59)

D. Allan Bryant – “Pitch Out” (17:45)

The two tracks on Source Record Number One are presented in the Spin guide as full albums, even though they do not appear to be such. At least, I could not find full albums with those track names. Or rather, there are Italian-only releases of albums with those titles, which also contain the track in question, but they are not on the Source label from 1968, as specified in the Spin guide. Anyway, I listened to those two particular tracks four times each.
