Matt first encountered Hess Is More at Monkey Town Brooklyn in 2007 — on the same bill as Julio Monterrey, who would become his long-term collaborator in Twos and Fours. He met Mikkel Hess at Cornelia Street Cafe shortly after and invited him to join a session with Twos and Fours. That evening became the beginning of a long creative relationship.

Hess Is More is led by Danish multi-instrumentalist and bandleader Mikkel Hess — a Copenhagen-based project that refuses easy categorization. The music pulls from disco, punk, jazz, and anything else that proves useful. It's danceable and strange, pop-adjacent and completely itself.

Matt is a full band member — playing tenor sax, soprano sax, clarinet, flute, effects, bass synthesizer, keyboards, and whistle. The instrumental range reflects the project's eclecticism: you bring everything you have and see what the music needs. He appears on multiple Hess Is More albums, including the 2020 release Apollonian Solos where he contributes two tracks.

The connection also runs through Worlds Put Together — Mikkel Hess plays drums on the debut album, listed as "Danish drummer Mikkel Hess (in whose pop band, Hess Is More, Parker plays)."
