I plan to update my prog ed thread soon and one of the things I'm gonna ad is
pop prog.
Or rather, the more commercialized prog that came around in the latter half of the 70s. A category which Supertramp, Kansas, Styx and Saga would fall into, Rush kinda fell into this category too, which is how they managed to survive the late 70s and early 80s when other prog bands couldn't, they embraced the pop but unlike Yes and Genesis kept the prog somewhat intact.
Journey also got their start as somewhat of a quasi prog band, but that stuff was so horrible, even the most diehard Journey fans don't like their first 3 albums.
