From Orlando Weekly:
In 1985, Lawrence D. “Butch” Morris, composer and jazz musician, directed his first “conduction.” That term, shorthand for “conducted improvisation,” was one he sought and received a trademark for – a new musical, rather than thermal-energy, application. You could initially reference Butch Morris as a uniquely voiced New York cornetist for Loft Jazz-era reedmen Frank Lowe and David Murray in the late 1970s. By the early 1980s, record collectors of this post-free jazz scene started witnessing the Morris name out front as a conductor, starting with violinist Billy Bang’s Outline No. 12 record. A larger discipline was set in motion, taking listeners years to completely grasp.
