It's a vinyl reissue of the 1995 Bay Area classic 99th Demention self titled album.
It's been remastered from the original DAT and Z-Man did the crazy art, inspired by the cassette cover.
There's a 60 x 30 cm poster inside too.
99th Demention is Z's high school group that he did with his brother King Maz and his school buddies (Rev Cope, Young $lim amongst others..). This is their first album (they did 2, the second being just Z & Slim).
Here's some of the reviews they had back then:
"Extremely dope (...) their originality and new flavor add spice to the life of Bay Area rap and to worldwide hip hop (...) their shit will make you laugh, nod ya head and think" (DJ Stef (RIP), Vinyl Exchange, 1995)
"A fantastic release topped off by great packaging and artwork (...) the lyrics are loaded with underground music politics but they still know how to have fun. Highly recommended!" (P-Minus, Atak catalogue)
It's available here, only 150 copies made:
