Yeah your right, my bad. Equalibrum, Emancipator & A Kid Called Computer all handle it, and they collaborate a little between tracks too, like first segment, second segment. And Varick Pyr does one track too.
I still stand by the The Art of Dying though.

DOOMs a funny one, some of his stuff I really like, other stuff I find a bit meh, Viktor Vaughn for example.

Remeber ALL CAPS when you spell his name! :laughing:

i think Jamie Fox and Kanye West's 'golddigger' was spot on.

Gang Starr are a group not a collaboration.
I also dont think Blackstar can be counted as Mos Def and Talib Kweli never made solo albums before the blackstar album

also theres

Redman and Methodman - blackout, blackout 2
Royce da 5'9 and eminem - bad meets evil
GZA an DJ Muggs - Grandmasters

Del and Tame One did a collaboration for one album, Parallel Uni-Verses.

It was pretty good for the most part.

The amount of writing done for him should mean Dre's albums are collab efforts.
