The Elder was horrendous. Almost but not quite as bad as Unmasked and Crazy Nights.
Rock And Roll Over, Love Gun, Hotter Than Hell, Dressed To Kill, Revenge, the self titled debut LP, Creatures Of The Night...all classics, top 100 LPs of all time IMO.
Curiously though, KISS does not occupy the Number One LP in my book. That esteemed honor goes to Holy Diver by Dio. If there is a bad note on that mutha I ain't heard it in the 24 years since it came out.
(Hmm...this might be interesting fodder for a new thread, one sure to get people ripping one another's throats out...)
