Essential Machine is RJ and Karen Dietrich.​ In 2007, they moved from Florida to the Pittsburgh, PA area, and the change of locale inspired the duo to start making music together professionally (they'd been harmonizing, literally and metaphorically, since they married in 2001). In the living room of a tiny apartment, Essential Machine wrote and recorded their first EP, Find the Harmony. It was released in June 2009, and they had more fun than should be allowed by law while touring the south in support of the record.
