The band was Dave Orr and John Hiebert on guitars and vocals, Trent Buhler on Bass and Chris "Lou" Lowry on drums. Pretty much and all-star lineup. This article from an 1986 issue of VOX, which explains a bit of their rich heritage, with members coming from Silent Terror and White Noise.
Of course, these guys would go on to bands like Stelazine/Skin Barn, Ninth Configuration, Field Day and, uh, Pal Joey.
This 8-track demo is a bit hissy, but it's still a great glimpse of a what must have been a pretty excellent band.
Also, based on the two photos above, they liked jumping a lot.
Update: thanks hugely to Trent Buhler for getting in touch and giving us a scan of the j-card for the tape!
