I haven’t got any Winterkat, but do have the Heyoka CD, think Winterkat had some members from Heyoka. Back in the late 70s early 80s SAN Antonio and Texas was a hotbed of hard rock, bands like Hooker,Ultra, Ozz Knox, Blackhorse, SA Slayer,Wyzard and Karion. Joe Antony pushed the boat out on his radio show and plugged some great bands.
