He was Guitar Fellow for the 2017 Bang On A Can Summer Music Festival in the US, and the group’s 2016 academy at Villa Musica in Germany , performing in works by resident composers Michael Gordon & Louis Andriessen.

His upcoming composer residency with Crash Ensemble consists of a multi-section composition for ensemble, drawing abstract and direct inspiration from evolutionary processes and soundscape ecology, and exposing contrasts and uncanny commonalities between ‘wild’ sounds in nature and human-made music and machinery. His exploratory approach to the guitar provides a connective tissue for this sprawling work which unites Crash’s affinity for vivid sonic colours with their powerful rhythmic drive.
