In June 2005 Anthony Braxton was invited to work with a 16-piece ensemble at Jazzatelier in Ulrichsberg, Austria. This work culminated in four performances beginning withthe solo piano and the trio and finishing withtwo performances with the ensemble. This 4-CD set documents yet another incredible achievement of Anthony Braxton, who, as Stuart Broomer writes in his brilliant notes, "has constructed a musical state in which no ultimate score can exist and in which the conductor himself is liberated - free to be surprised by the ongoing shaping of the music as well as its detail".
