Summary: For this New Sounds program, listen to “Mixed Music” – a term coined by musician/composer Joseph C. Phillips Jr. -which is a blend of jazz improvisation and groove-based minimalism or other forms of composed music. There’s brand-new music from the Brooklyn-based Peter Kerlin Octet, an outfit consisting of two vibraphonists, two bassists, an organist, a drummer, a percussionist, and a violist. On his record, “Salamander,” bass player/composer Kerlin offers up ambitious bass-driven compositions that weave through post-rock and minimalist territory, with improvisational jazz-like detours along the way.
