Oh hell yeah! The first album with Bolin really had some hard rockin songs in the mix (Moonrider etc.). They had a stadium rock vibe (in a good way) that was really ahead of their time. Oddly, Bolin's distinctive high pitched guitar isn't featured all that much. I haven't listened real hard to Moxy II; but I can tell that it's almost as good, similar dynamics. Ridin High is the heaviest; but for me the riffs aren't very original (but still good riffs). After Buzz died, they added Mike Reno pre-Loverboy; which hurt their power credibility and killed them off. To be fair I've never heard the Reno album, but I assume it's not as heavy.
