That would be Marshall Allen
From Weasel's site: Firestorm is an intense and musically assaultive release of killer, balls-out free jazz that will appeal to those who long for the most bombasic works of Broetzmann, Ayler, Takayanagi and Cecil Taylor! This release reveals many shades of intensity and mood while remaining frenzied and inventive at all times. Featuring Taylor alumni Marco Eneidi (alto), Marc Edwards (drums), Lisle Ellis (bass), Elliott Levin (tenor), Sun Ra Arkestra legend Marshall Allen (alto), bassist Damon Smith and manic Austrian reedist Mario Rechtern, Firestorm is a delerious concoction of new energy music that pushes beyond the stratosphere of sound!
