‘‘Aran’’ and ‘‘McCrimmon Will Never Return’’ date from the period 1970-72, and were written for the Promenade Theatre Orchestra, a group started by White, consisting of 4 performers; White, Hobbs, Hugh Shrapnel and Alec Hill.
‘‘Aran’’was written at a time when the PTO was beginning to combine the sounds of reed organs and toy pianos, the original instruments of the group, with some newly-acquired percussion instruments. The note-to-note procedure of the piece was determined by random means, in the hope of producing a gentle unpredictability in the final result. It was hoped that the whole would be grittily resonant. This recorded version, for 12 performers, is generally more soft-centred than the original.
