A new collaboration including Tuscaloosa colleagues Holland Hopson, Andrew Raffo Dewar, and the legendary composer and saxophonist Anthony Braxton grew from his spring 2015 residency at the University of Alabama. In early August 2015 the quartet recorded four hours of new music, combining improvisation, fragments of music from older compositions, and a new system of performance logic and graphic notation unique in Braxton's output. The resulting music, Compositions 398-401, will be released in a set by the Tri-Centric Foundation, QUARTET (ZIM) 2015.
Feeney and Dominic Lash recorded James Saunders's overlay (1) / overlay (2), for several layers of contrabass and bass drum sound. The Rhizome.s label released the piece as part of Lash's Performance in January 2016.
