The Step Brothers (The Alchemist and Evidence) are set to release their collaborative project 'Lord Steppington,' which is due out in stores Jan. 21. The duo just released a new single called 'Mums in the Garage' featuring Action Bronson.

On the track, Bam Bam comes through with an irreverent rhyme that consists of girl scout cookies, dodging cops, getting a testicular exam, smoking weed and having sex with fairies.

Then Alchemist follows with a crazy verse in which he name-drops Al Bundy and Jimmy Walker. "The city stalker with a violent life, silent knife / Uptown escape, but this ain’t Harlem this is solemn nights," he raps.

Meanwhile, the Alchemist spits hardcore rhymes about removing body parts. "Mad man I rip up stages / Specialize in removing lips and faces," he raps, adding, "Karate chop the nipple off your chest / Ring the alarm this is not a test."

If you like this throwback-sounding joint, peep the duo's previous tracks, 'Ron Carter' and 'Nothing to See/Hear.'

The Step Brothers’ LP, 'Lord Steppington,' boasts guest appearances from Roc Marciano, Styles P, Fashawn and Blu. The album is available for pre-order via iTunes.
