Criminal Activity is the only studio album by American rap supergroup Criminalz, which consisted of Spice 1 and Celly Cel.

Cel also served as executive producer and audio production of the record was handled by Doyle, G-Man Stan and Spice 1.

One song, "Boss Up", was previously released on the Spice 1 compilation, The Playa Rich Project.

Allmusic - "Everyone was expecting a lot from this group from the first time it was mentioned...For many reasons this just doesn't work...It seems like they all wrote their verses independently of one another, then rapped in whatever order they felt like it.

The Criminalz definitely lack a mastermind to weld the three of them together and make them realize their synergies...There are almost no ad-libs, there's no interacting, it might as well be that these three never were in the same studio together..."[4]
