Although John McCabe's Rainforest II, of 1987, is in effect a chamber concerto for trumpet and 11 strings, his extensive body of concertante works has lacked an official trumpet concerto. La Primavera, which had its première on 15 June 2012, now happily fills that gap. The subtitle derives from McCabe's consideration of two aspects of the approach of Spring: the vitality of burgeoning growth and the flowering of the new or refreshed life as it expands.
