Lead guitarist, keyboardist and singer Guy McDonald and his best friend, lead singer and guitarist Stan Sherby, both come from Minneapolis. They were able to present their musical ideas of a kind of progressive hard rock, sometimes together with local bands at McDonald’s father’s nightclub. Over the years, they gained a strong local following and also caught the attention of major record labels. In 1970, they went to Minneapolis’ Sound 80 Studios and initially recorded a single. During the recording sessions for their subsequent six-track debut album, they were supported by four backing musicians: Sly Williams, Dan Dropiek, Monty Edwards and Dan Olson.

They played excellent heavy acid rock with progressive elements and impressive heavy fuzz guitars. Gentle passages alternate with psychedelic hard rock songs. However, as a record deal never materialised, Guy decided to have a limited number of LPs pressed for family and local supporters. Their only album Catharsis was not released until 1974 on the Omniscient Records label, which was founded especially for this purpose. In contrast to the cover design, on which the two bearded musicians look more like a parody of the counterculture, the LP impresses with its musical quality and the impressive instrumental skill of the duo. This ultra-rare private pressing is now regarded as one of the best guitar-driven heavy psychedelic prog rock albums from 1974. And one of the rarest too!
