To be sure, there were lots of period rockers that found their success in killer base lines and chunky guitars. But, bands like Asia and GTR played in treble-land, merging power chords with a soaring guitar riffs.
A lot of this was clearly Steve Howe (ex-Yes and a central figure in both bands)...but it certainly wasn't completely his influence, as his prior and subsequent solo work never attained the success of any of his bands.
Enjoy. And have a sheen-y weekend.
