2013, the duo of Parsons and Hayes invited singer-songwriters Gwyneth Moreland, for whom Hayes had produced the album "Ceilings Floors and Open Doors" (2014), and Steven Bates, a long time California club headliner, to join them in four-part harmony vocals and a showcase for each member's songwriting. The Mendocino Quartet was born and in 2017 released their first CD together "Way Out There." Hayes produced a 2015 EP of live performances for Moreland called "Stages" that featured concert recordings with all members of The Quartet and, in 2017, he produced Gwyneth Moreland's "Cider." Both Ceilings Floors and Open Doors and Cider won the two of them accolades including topping Folk singles and album Charts.
