Most Albums by one Artist

That would be Zappa and then probably Neil Young but if I include mutiple versions of the same albums Yes and Rush will be up there.

Hawkwind and King Crimson. I have multiple copies of some albums, including 4 copies of Hawkwind's first album (original release LP with gatefold sleeve, re-release LP with single sleeve, picture disc LP and CD reissue).   

Oh i have many of many artist probably Zepp  with all the official releases and 110+ shows.

Rush: about 22 albums

not sure, either Hawkwind or Peter Hammill, whoever made more albums. there is a fair amount of other artists with lots of albums in our collectrion too, like Frank Zappa or the Ozric Tentacles. we are completionists; we only make an exception when an artist starts producing only albujms we don't like (like Tangerine Dream, for example; after "Poland" they changed their style drastically, and not to their favor, however, that still makes a lot of Tangerine Dream albums in our collection. Gong and Guru Guru are another big bunch. no bootlegs though

Zappa.  No contest.

I forgot who it was, but he's still around and dropping new albums. In his lifetime there would probably be thousands.

That is ridiculous...

CD Universe people will be happy to nominate Dream Theater. On their all-time best-selling chart, Dream Theater is like ... they own the website or something. Note that O.S.I. and A Night with John are actually Dream Theater in different forms.

For me, it is Yes and Yes-related.  I have all of the Yes official releases as well as a few bootlegs and some of these crazy unofficial compilations that have also been released.  I have also been on a mission to try and collect as much Yes-related albums as I can.  I have most of the Jon Anderson solo albums, Steve Howe solo albums, and Bill Bruford solo and Earthworks albums, as well as the Chris Squire and Alan White side projects.  Not to mention the Bill Bruford side project band called King Crimson (or something like that ).  I have many Rick Wakeman solo albums, but quite frankly I've probably barely made a dent there since there are so many releases, and many of them are out of print.  But essentially, if a person was ever a member of Yes, I am pretty much trying to collect any CD/album where they may have made an appearance.  I have many, many CDs here to that effect, but unfortunately, I still have a long, long way to go.

Fo me it is David Bowie, with all his studio recordings, some live, some greates and some boots
