I felt the same way about GTR. You had Steve Hackett from Genesis and Steve Howe from Yes. On paper it had great potential, but it fell flat.
I recall an album from the 1980s, a collaboration between Sammy Hagar and Journey axe-slinger Neal Schon. It was recored live and delivered an absolutely incendiary rendition of "Lighter Shade of Pale." Actually, the band was HSAS (Hagar, Schon and 2 other dudes I'd never heard of).
They only released that one live album and it was pretty good, IIRC.
