These two fine new releases situate soprano saxophonist Gianni Mimmo in small ensemble encounters with the extraordinary improvisers Garrison Fewell, Martin Mayes and Lawrence Casserley. Flawless Dust sees Mimmo in a duet with the late Fewell, an American-born guitarist who lived and taught in both Europe and America. Recorded in Novara, Italy in October 2014 and dedicated to Fewell’s memory, the music develops through the creative confrontation of two voices along several axes of contrast: Of timbre (Mimmo’s reedy, serpentine lines against Fewell’s prickly points of sound), duration (the breath-carried sustain of the saxophone again the guitar’s short, pizzicato eruptions), and phrasing (the legato of the wind instrument against the staccato of strings). Granularities: A Trialogue is, as the subtitle indicates, a trio date featuring Mimmo with Mayes on French horn, hand horn and alp horn, and Casserley on percussion and granular signal processing, recorded in September, 2010 in the UK. The intersection of the two wind instruments, which often interweave smoothly phrased lines, and the atmospheric interventions of Casserley’s granulations, make for a multifaceted but ultimately integral overall texture that Mimmo in the liner note aptly characterizes as a “complex event.” The constant running through both these rewarding sessions is Mimmo’s distinctive voice, which remains unfailingly lyrical at heart no matter how abstract the surroundings.
