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, one stated that the band wrote about "getting closer to God and not rejecting the Truth.
