Mat Muntz is a composer, bassist, and bagpiper. Rooted in jazz improvisation and extending through microtonality, non-Western instrumentation, and experimental performance practice, Mat's work seeks to imbue the volatile and bizarre with an expressive, human immediacy. His music has been described by The Wire as “rare and rewarding,” and “with a weirdness which is positively thrilling,” and by The Guardian as “filled with a wild, distorted energy.”

Mat has performed across North America, Europe, and China at venues including Carnegie Hall, the Kennedy Center, Roulette, Blue Note Beijing, and the Umbria Jazz Festival. As a composer, he has written for ensembles including Yarn/Wire, Del Sol Quartet, and Wet Ink, and is a co-leader of the cross-cultural experimental ensemble The Vex Collection with Vicente Atria. His debut album as a leader, Phantom Islands, was nominated for a 2024 German Jazz Prize for International Debut Album. Mat's projects have been awarded by The Shed, Brooklyn Arts Council, and NYSCA, and in 2022 he was invited to attend the International Gugak Workshop in Seoul. He holds degrees in Jazz Bass Performance from Manhattan School of Music (BM, 2016) and Music Composition from UC Berkeley (MA, 2024).

Since 2018, Mat has pioneered an experimental practice on the obscure and distinctive Croatian bagpipe known as primorski meh. An ongoing exploration of the instrument’s unique intonational, timbral, and technical possibilities is documented in a growing body of solo, ensemble, and electroacoustic music – documented on the recordings meh. (2020), ghostly.ridiculous (2021), The Vex Collection (Carrier Records 2022), Phantom Islands (Orenda Records 2023), and Angels Variations (2024)
