Here is a band I had never even heard of, and I was living in the 80s bay area/sacramento metal scene. I dug into their Wikipedia page(!) and found this:
Winterhawk was an American heavy metal band formed in 1978 in San Francisco, California. Fronted by lead vocalist, lead guitarist and songwriter Nik “Winterhawk” Alexander (a Cree musician), the band released two albums via Mother Earth records.
Winterhawk was committed to a native anti-drug movement, pioneering an abstinence-through-music platform that ran parallel to the straight edge hardcore movement. Winterhawk performed in the 1983 US Festival and has opened for Tina Turner, Santana, Country Joe and the Fish, Steve Miller and Van Halen. The band separated in 1984.
Wait, WHAT? First of all, they were the Minor Threat of the Native American rock scene, which is amazing… but they played the US Festival? Maybe I am the one who whiffed on these guys… never heard of ’em.
Anyway, like most of Doug’s tapes, this one was a good candidate for an EQ + rebalance job. The drums were super loud in the mix, so I did what I could with it.
One last thing- also never heard of the Chi Chi club. It was across the street from the Mab/On Broadway and hosted a bunch of dead-related jammy stuff.
