Using multiphonics, extended techniques and an intuitive sense of drama and narrative, Barcelona alto and baritone saxophonist Don Malfon takes his listeners on an 8-part journey of "Mutable" solo performances, using every inch of his horn (including inserting resonant objects), his body, tongue and breath to investigate the outer limits of his instruments.

Vibraphonist Emilio Gordoa leads this superb quartet with Don Malfon on alto & baritone saxophones, John Edwards on double bass and Dag Magnus Narvesen on drums, in an incredible live performance at the 2019 Alte Gerberei Artacts Festival in Austria, a captivating set of creative techniques yielding well-controlled passages of both intense activity and unique introspection.
