After playing a role in the success of Yes' Relayer album in 1974, keyboardist Patrick Moraz launched a solo career and became one of the more celebrated keyboardists of his age. During the '70s, when Moraz reached his prime as an artist, the keyboard was still a new and complex instrument. Technology was still evolving in the age before the personal computer. For this reason, Moraz's trailblazing keyboard work startled his audience. He practiced a new and exciting sound that was ahead of its time, owing a bit to the era's prog rock sound. However, that prog rock sound soon lost its novelty as the '70s became the '80s, and Moraz had to adjust to the times on his '80s solo albums. At the same time he found security in the Moody Blues, a legendary band whose ranks he joined for a few albums.
