Trytan was a Christian progressive / pop metal / hard rock band from Chicago, Illinois. Musically they were similar to Rush. The band was ministry oriented, and had what Christian music critic John J. Thompson characterized as a significant impact on their scene. Their second demo (1987) was reworked for release by R.E.X. Records under the name Celestial Messenger. It featured a metal sound typical of the hair era of metal. Their debut's lyrics also reflect their ministry orientation
