Golden State was a record label BUT it was also a recording studio (both run by Leo Kulka out of San Fran). He also had the Golden Soul label & his own mastering service (Sonic Arts out of the same building @ 665 Harrison Street, San Francisco).
His label seemed to use around 8 / 9 different numbering systems but by the late 70's, the label was using numbers more like #437. None of their systems used any number like 201.
So, I'm guessing that this could even have been cut at Golden State but not destined to come out on the GS label (which seemed largely in-active at the time). The record that did escape on the label in 78 was by female Joy Higgins and it obviously ain't that.
I quite like it, it has a sort of jazzy (70's) Terry Callier type of vibe. Bet the likes of Colin Curtis would go for it.
