But on this trip, Vida's bringing only himself and a passel of horns. For his Saturday NMC show, Vida will be performing solo excerpts from his "biotechno-illogical love story" of an opera, Clown Monkey. A five-year work in progress, Clown Monkey avails Vida of a "poetic logic for interpreting sound space." Who knows but that it might also provide him the opportunity to wield his tone, that densely veined, metal-studded column of breath issuant from his tenor. Given that he's traveling with six instruments and a stated vocation as a storyteller, expect something happening. He'll also be in workshop at Washington University on Friday, discussing extended notational techniques (check out www.vidatone.com). Vida's ready; you're late.
