and i happened to be doing a lot with the scottish chamber orchestra, and they happened to be workingsh composer, so we thought, "why don't we askjames to write a percussion concerto?" and i remember saying to the scottish chamber orchestra that, honestly, if there is one composer who could write a concerto, it has to be james. and, of course, both our thinking came together and he wrote a piece called veni, veni, emmanuel. and, yes, this was the first—ever percussion concerto in the history of the proms, and it gave orchestras faith to put percussion concertos on. this is a piece of music that is absolutely incredible for every orchestral player. it's a real challenge. it's almost like a concerto for orchestra, in a way. erm, it's such a meaningful piece as well. how many instruments were you playing on stage that night? oh, my goodness. erm. .. i think i was probably too busy to count. heavens... i think there must be around, maybe... i don't know, 15, 20 different instruments or something. and you're rushing backwards and forwards across the stage. it's a physically demanding piece
