I first encountered his music in the form of his Suite for Guitar, op 41, written in 1986. I did the West Coast premiere of the work at a contemporary music festival at the University of Victoria in, I think, 1987 or 88. In 1989 I played the piece in a solo recital at McGill University in Montreal. This was the occasion when I met M. Hétu as he not only attended the concert, but he came backstage afterwards to talk to me. He was quite complimentary and we had an interesting chat about the piece. Alas, I never got around to recording it. Here is a performance by Andrei Burdeti:
The composer that most reminds me of Hétu is Dutilleux. They are both lyrical, meticulous composers, not prolific, but the creators of lapidary delights. The Suite for Guitar is a fairly minor piece, for a better idea of his range as a composer we should listen to his Symphony No. 5, which might have been his last finished work. This is the premiere performance with the Toronto Symphony Orchestra, Peter Oundjian (Conductor), Amadeus Choir and Elmer Iseler Singers.
UPDATE: On reflection, I have actually met a few more composers: my old friend Canadian composer Anthony Genge, Cuban composer Leo Brouwer, English composer Stephen Dodgson and probably a couple of others. Oh, and Karlheinz Stockhausen.
