Mostly metal bands in this thread, so I'll mention Sanctuary. One great album in '87, Refuge Denied, and a followup that seemed to be building them some momentum, then 1991 happened and they split up when the record company pushed them in a trend-chasing direction. Warrel Dane could hit high notes like the love child of Geoff Tate and Rob Halford. If they'd come along 2 years earlier they could have really gone somewhere. In a non-metal rock vein, Cry of Love. They've been called southern rock because they came out of North Carolina, and monster guitarist Audley Freed stepped into the Black Crowes for a few years in the late 90s, but they were more straight-up hard rock than a Skynyrd/Allman/Molly-Hatchet/Marshall-Tucker vibe. Their debut album Brother came out around '91 or '92, they toured relentlessly supporting acts like Aerosmith and Robert Plant, and had a minor hit with "Peace Pipe," then their singer quit after the tour, they lost momentum, and the record company didn't know how to promote them to build on their success.
