Yes it became a little bit "prog-rock", and I think That Alan Clark had an important impact on compositions.
early 80ies were not really the ideal era for prog-rock. bands like Yes, Genesis, King Crimson ditched the long intrsumental passages, and the trendy music at that time was disco or punk-cold-wave music, so I always wondered how such albums like LOG or Alchemy with long guitar solos made big hits while the "dominating" music at this time was the exact opposite : synths, "FM-calibrate" shorts songs, etc...
