Genius.
Here, here.
The thing is allot of people like to shift the blame for a bad album at the producers feet but grab all the accolades for a great album as proof the artist is a genius.
The truth (as always) is a 3 edged blade and it sits somewhere in the middle of both these reactions.
Bob ezrin does what it says on the tin. Professional, great sounding production with allot of depth. Managing to meld disparate instruments yet produce a clarity rarely seen (especially in the early 70's)
He tends to have a hand in writing (which is another stick to beat him with) but he will write in the direction the relevant band is heading in.
Even on a "bad" bob ezrin album like "....music from the elder" the production did exactly what kiss wanted it to be, clean, precise and bombastic (basically unlike any kiss album before it)
in terms of sonics, Bob doesn't make odd musical choices (like excessive hand clapping, or soulless guitar tones - we are looking at you ACAS)
Welcome 2 my nightmare was a master class in production. Clean, precise, energetic and emotive. Fresh and modern when it called for it and classic old school when it didn't.
Paranormal is another slice of production gold. strong clear sounding tracks (even while pulling out the fuzz box guitar tones)it has a punch and energy not unlike flush the fashion and that classic 70s sound that alice was so clamouring for.
