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.

A fully improvised cycle of seven miniatures, or "Mutations", recorded live on Kultur-Schranne in Dachau, Germany in 2019 by the trio of two masterful and legendary players--Catalan pianist Agusti Fernández and British double bassist Barry Guy--inviting young Catalog saxophonist Don Malfon as they transmute their conversation for fascinatingly creative conversation.
