Trey joined the Vermont Youth Orchestra, conducted by Troy Peters, on electric guitar for the world premiere of the Ernie Stires composition Chat Rooms (i. The Blue Room; ii. The Green Room; iii. The Red Room) and the Stires/Anastasio composition Samson Riffs (i. Samson Riff, ii. Samson Variation, iii. Samson Counterpoint). The debut of Guyute (Orchestral) – on which Trey did not perform – featured a reintegration of this original 1992 piece that had in the Phish repertoire evolved as My Friend My Friend. Trey performed acoustic guitar for The Inlaw Josie Wales with featured accompaniment by Adriane Post and Jane Kittredge on violins, Anja Jokela on viola, and Indigo Ruth-Davis on cello. This recording of Guyute (Orchestral) was later released on The Mockingbird Foundation's Phish tribute album, Sharin' in the Groove.
