Anthony Braxton, prodigal son of the AACM movement and MacArthur grant recipient, has just released his very first recorded opera, Trillium E, in the form of a four-disc box set. He seems to understand the financial, as well as mental, undertaking customers require when encountering works like this, so he has decided to release a free career sampler. Composition, Improvisation, Synthesis: Selections from the Tri-Centric Foundation Archives runs the gamut of his numerous instrumental works (identified only by number) as well as an improvisational piece and excerpt from Trillium E itself. All it will cost you is a little bit of personal information, and all 79-plus minutes of this wonderful, wild music is yours.
An NPR story mentioning both Trillium E and Composition, Improvisation, Synthesis: Selections from the Tri-Centric Foundation Archives can be read or downloaded here.
