David Jackman, Untitled B

Am busy working on my next musical release. Some experiments with Doepfer's cv-to-midi module, and getting back into the Machinedrum (because it's there).

Was randomly checking out "noise" releases from Mr.Schwarz's YT page.
Found "Untitled B" from a 1983 cassette by David Jackman. [YT audio]
Based on the runtime it appears to be from this tape release listed on Discogs.
Echoing squeaks (possibly violin) overlap and fade, swaddled in tape hiss. Artfully degraded analog sound quality typifies the era and medium.
An accompanying photo on YT shows Jackman outdoors "playing" a mixing desk. No idea whether it relates to "Untitled B" or if it's just a publicity photo from that time period.

What led me to Mr.Schwarz (no space) was his YT of Oeo by Sukora, a vinyl record (which I have) on the LoVid-related Ignivomous label. Amazingly this was reviewed by Discogs user Intransitive:

One side is an arrhythmic tapping on what seems to be a contact mic with no effects on it. the other side seems to be the sound of a record's run-out groove. It's simple, and yet... this is an enjoyable record! I especially like the first side, which instead of being precious, manages to create a certain calming atmosphere. There's no concept or pretense, either. It is what you think it is. Nice.
