For those that don't know, Promatic are Proof from D12 and underground legend Dogmatic (formerly Big Stoney). What started off as a collaboration for one track, became a 20 track album. The whole album was produced by Sick Notes; a new producer form Detroit who has a varied style that complements both Dogmatic and Proof perfectly..

Staying true to their roots, 'City of Boom' and '313000' are their odes to Detroit, making the world know they're not the first, nor the last to come out of the D this year.

The rest of the track line up is a virtual myriad of topics and themes. Neither of these talented MCs is ever short of something to say, they can even make funout of your favorite movies on their interludes, and completely exaggerate drug usage on "Waffle House"; not to mention get off deep into life philosophy, and their interpretations of the build up to 9/11, and the ills of the world on "Life".

"Do What I Wanna" is a cartoonish song about rebellion, similar to a 2002 version of Fresh Prince's "Parents Just Don't Understand" with a few more cuss words and drug references. "Dirtiest Grimiest" takes the album back to D12's "Devil's Night" album and resembles "Fight Club" without the guitars.

Bottomline:For all you people who thought D12 was just Eminem and some other people, Proof makes a serious impact on this album. This is clearly what Hiphop has forgotten about.
