The Alchemist and Evidence's new collaborative album — 'Lord Steppington' — was a long time in the making. It finally hits stores Tuesday (Jan. 21), but fans have the opportunity to stream the album in full.

The duo collectively known as the Step Brothers have collaborated frequently for two decades — dating back to their start as young emcees in Beverley Hills, Calif. The Alchemist has produced some of Evidence's best tracks, including 2004's 'This Way' featuring Kanye West and Evidence as a member of the Dilated Peoples.

West doesn't make an appearance, but 'Lord Steppington' is stacked with like-minded emcees. Action Bronson, Roc Marciano, Styles P (some may remember he and The Alchemist assisted New York classic 'We Gonna Make It'), Scott Caan to reunited The Whooliganz, Blu and plenty others.

'Lord Steppington' comes with 14 tracks, including the already released 'Mums in the Garage,' 'Step Masters' and ‘Ron Carter.‘ Check out this piece of boom bap, rappity-rap goodness below.
