Integer Collaborative Ensemble

Integer began in 2018 as a Portland-based piano trio with Todd Marston (compositions/piano), Andrew Jones (acoustic bass) and Micah Hummel (drums). Through the years, the foundational solidity of this rhythm section has allowed Marston to explore a variety of larger iterations of the group. In 2021, Integer Septet released Solidarity Themes, and more recently Integer Quintet has recorded an album to be released in 2024. Integer Collaborative Ensemble has been assembled specifically for the 2024 residency at Doe Bay as a way of unlocking the compositional gifts of all of its members.
