Fans of muscular progressive rock will love Solar Fire, a concept album loosely designed around cosmology. The album opens with the majestic "Father of Night, Father of Day," which has the drive and complexity of a prime King Crimson track. As unlikely as it may seem, the track was controversial in Mann's native South Africa because of the "Father of black, father of white" line, implying that apartheid might not extend to infinite space. The album moves on to the progressive rock/jazz fusion of "In the Beginning, Darkness," a swinging, even funky track that benefits from soulful vocals by Doreen Chanter and Irene Chanter of the Grove Singers. The same duo contributes to the title track, a slow piece that begins with a fairly standard rock structure and incorporates a massive progressive jam in the middle.
