Based in the Pacific Northwest, Glass was formed in the early '70s with the lineup of Greg Sherman, Jeff Sherman, and Jerry Cook. They began a musical path down the road of progressive rock. After a time, Cook left the group and was replaced for a time by Paul Black. The group did not last long in this configuration, though, and called it quits shortly after. In 1999, Glass reformed and released the album No Stranger to the Skies the following year. ~ Gary Hill
