From what I understand this was recorded as something for the band to send around to labels to score a record deal and was never released as a demo.
5 songs, one that never saw the light of day. The others you know from the ep and the lp.
A little history from the rev site....
Supertouch started in 1985 out of the ashes of New York hardcore band Death Before Dishonor, which featured a young Mike Judge on drums. They released a demo and some WNYU tapes, but no actual records. Supertouch, named after a Bad Brains song, had a different drummer than DBD, since Mike went on to Youth of Today and later, Judge, but it still had the Yu brothers on strings and of course Mark Ryan on vocals.
