An extended work for 10 improvisers using a composite composition of graphic scores, open notations, and two trio sub-pieces titled "skelf" (electric guitar, double bass and drums) and "antiphon" (violin, viola and double bass), all directed by UK saxophonist Matt London in an ensemble with reeds, winds, brass, strings, electric guitar, and Mark Sanders on drums.

The second Masada book project from the adventurous London big band Spike Orchestra, whose interpretations of Zorn's Book of Angels compositions in their Cerberus album was a high point in that series by presenting lyrical strength, skill and power, heard again merging jazz, rock, & klezmer & more as they take on 9 compositions in Zorn's Book Beriah series.

Led by composers Sam Eastmond and Nikki Franklin, The SPIKE Orchestra is a large ensemble that draws on a wide range of influences including Duke Ellington, Frank Zappa, Carl Stalling, Zorn and more, here performing the 26th "Book of Angels" covering Zorn's Masada book.
