This survey of Runswick's piano works demonstrates the sheer breadth of his musicianship. The title track, dot music (2001-13), with its specially-devised dot notation, was inspired by the pianist Julian Jacobson's request for a companion piece to Beethoven Sonata opus 111. In contrast, the Sonatina (1981, rev 2013) integrates Mozart and jazz.

Having performed and worked with composers such as Boulez, Berio and Stockhausen, Runswick's Six studies on b-o-u-l-e-z (2016) forms a tribute to the late composer and a compendium of Daryl's own composing styles: total serialism, aleatoricism, modernism, jazz, and a nod to Peter Maxwell Davies. The CD is rounded off with Introduction and Fugue in B minor (1967, rev 2003).
