Jonathan Harvey's Ricercare Una Melodia for Trumpet and Tape Delay.
Published by Faber Music.

'The ensuing web of melody at first intertwined with the Trumpet in close canon, and then - by the device of running some of the tape tracks at half-speed - plunged far below the Trumpet's plangent incantation: an effect that was both cogent and beautiful.'

~Malcolm Hayes, Daily Telegraph, 11 September 1989
