I just purchased Twelve Dreams of Dr. Sardonicus by Spirit, 5cd box set by The Sensational Alex Harvey Band (=their first five albums) and a 3cd compilation by Mott the Hoople/Ian Hunter. Some examples of those, respectively:
Somehow TSAHB reminds me of Alice Cooper (the band) a bit, but less hard rock-y and a bit more cabaret
Not a fan of Ian Hunter's singing (kind of like David Bowie on a bad day), but as a songwriter, pretty good.
The later (version) "Cleveland Rocks" is probably better, but this is okay too
