Sudoku 26 was produced on March 26 2006, as a gift for John White on his 70th birthday on April 5. All the sounds are samples, mostly from GarageBand. There are 70 sounds (though not 70 different sounds) in the piece, randomly arranged as far as placement and duration are concerned. The mixture of serious and silly, music and sound effects, was intended to give a rough idea of the diversity of White’s musical world (Christopher Hobbs).
