As individuals, multi-instrumentalist Robbie Lee and guitarist Mary Halvorson have revealed well-developed appetites for experimentation throughout their careers. Lee is a multi-instrumentalist who specializes in saxophones, several kinds of reeds, woodwinds of contemporary and historical vintages. and organ and guitar. He has worked with everyone from Cass McCombs and Josef Van Wissem to Eleanor Friedberger and Neil Hagerty. Halvorson leads her own trio, plays in the Thumbscrew quartet and a duo with Jessica Pavone, and worked in bands led by Taylor Ho Bynum, Marc Ribot, and Susan Alcorn. Seed Triangular is her seventh release of 2018, following a pair of simultaneously issued Thumbscrew records, two duo albums with guitarists Bill Frisell and Joe Morris respectively, as a member of Ingrid Laubrock's quartet (with Nate Wooley and Kris Davis) on Contemporary Chaos Practices, and most notably for her own complex, double-length song project Code Girl. Lee and Halvorson have not recorded together before, but have improvised together and with other ensembles for a decade, developing a respectful, intuitive musical language in the process.
