Aaron was born in Mykonos, Greece, and began his relationship with music after being exposed to classic 70′s soul music,Prince, and the pop music of the 80′s. A few months after his fifth birthday, Aaron moved with his mother and stepfather to the United States, settling first in Chicago. He began his formal training on the saxophone at age of eleven, as a middle school student in Chesapeake, VA.
As a student at Berklee College of Music, Aaron co-founded Sistine Criminals, a drum and bass project rooted in his collaborative relationship with the drummer Greg Sgrulloni. During this period, he also met current collaborators including the pianist Carlos Homs, the drummer/multi-instrumentalist Tyshawn Sorey, the guitarist Andy Berman, and the bassist Nick Jozwiak around this time as well, who are all members of the group Aaron calls “The Big Machine.”
