Nancarrow's music for player piano with .acrobatic complexity .that sounds .hardly performable has been known for more than four decades. The traditional notation is replaced by the accurate manual punching of individual holes in player piano roles, thus enabling multi-part sounds and rhythmic counterpoints in irrational relations which could never be played so accurately by human performers.
Fortunately, Nancarrow's less complex studies are again and again arranged for a wide variety of live instrumentation. The arrangement for two pianos by the renowned British composer and conductor Thomas Ad�.s (*1971) presents the ideal opportunity for every experienced pianist to not only listen to the studies but to play them as well.

Garth Knox is one of the most prominent violists of his generation, and as former long-time member of the Arditti Quartet he has developed and maintained a fondness of contemporary music. In the meantime, he gives concerts and teaches courses all over the world.

With 'Viola Spaces' he wants to make contemporary playing techniques accessible to advanced players. The pieces, or 'playing spaces', are true concert studies, each of them dealing with specific techniques such as harmonics, pizzicato (with 9 fingers!) or tremolos which are explained in great detail.

Another volume with modern playing techniques for two violas and a volume with variations on a piece by the French viola da gamba master Marin Marais for four violas are planned.
