As a prelude to tonight's edition of Hear and Now, Pre-Hear festures music by two composers associated with the English experimentalist tradition. Michael Nyman has carved a niche for himself with his personal take on driven minimalist textures, and the characteristic sound of his 'outdoor' band has defined his music as like no other. At the other end of the spectrum, Laurence Crane's enigmatic miniatures seem to float outside time, relishing sweet and astringent harmonies for their own sake. Laurence Crane: Kierkegaards Michael Finnissy, piano Michael Nyman: 3 Quartets Michael Nyman Band.
