Hailing from the South Side of Chicago, up-and-coming duo M.A.R.S. (Music Always Reigns Supreme) introduce their out-of-this-world sound to the Booth with newly-released mixtape single Do It Man. Here, partners-in-rhyme Ayo-Kid and London Boy deliver swag-drenched bars over a clattering, sampled beat by the latter’s producer alter-ego, Mr. Williams. For more, check out M.A.R.S.
