"The enigma that is Tyshawn Sorey: while most young drummers are walking in the footsteps of the elders," writes Mark F Turner, "Sorey thrives on the outside, composing and performing free improvised music. His debut, That/Not, exposes the inner workings of a young musician with the ability to play in any context, but the boldness to do his own thing." Born in 1980, Sorey plays drums, piano and trombone, and has recorded with Muhal Richard Abrams, Wadada Leo Smith, Dave Douglas, and Butch Morris, among many others. "It's a two-disc manifesto of some downright iconoclastic music," writes Nic Jones about That/Not. "The pervasive feeling throughout this programme is that Sorey and his colleagues have arrived fully formed on the scene."
