The album had a diverse sound, it showcased the style of two band members and a pre-commercial sound: James Young songs were more straight ahead hard rockers, while Dennis DeYoung songs were more mellow ballads, classical, and prog rock songs.
The original issue contained "Best Thing", a song also contained on the first Styx album from 1972, as the opening track on side two. A second release of Man of Miracles substituted this with the catchy upbeat song "Lies", originally recorded by The Knickerbockers in 1966. The album was again reissued in 1980 with new artwork and a newly abbreviated title, Miracles. This version started the second side with the ballad "Unfinished Song", which is sung by Dennis DeYoung.
