That would've been funny!
MMM: Don't bother checking out Bruce's solo stuff because its nothing special. Average (not bad but nothing special) songs with below average vocals but some cool guitars. However his live shows rock coz he plays mainly stuff from when he was in Kiss as you can see from the setlist and has a great singer.
If you wanna check out a Kiss member's solo stuff I don't think I even have to say who is the best one to check out.
Vinnie Vincent obviously! But also Mark St. John's post-Kiss band White Tiger are really good, and Paul Stanley's 1978 solo album rocks too. Ace's solo stuff is pretty boring and no need to even mention Peter coz he sucks balls. I haven't heard Eric Carr's Rockology album yet but apparently its pretty good...
Vinnie Vincent easily did the best stuff outside of Kiss though. He also had the most commercial success as a solo artist too out of all the Kiss members, which really says alot about the quality of his solo work because he was the least liked member of Kiss ever.
