Aaron Rose, formerly known as A La $ole, is a member of the New York collective Pro Era, alongside Joey Bada$$, Nyck Caution, Kirk Knight and many others. Just like most of PE’s members, he is from Brooklyn.

Rose featured on four songs from PE’s P.E.E.P: The aPROcalypse, rhyming with witty lyricism over raw boom bap beats.

On December 16, 2016, Rose dropped his debut, Elixir, alongside producer J57.
