There are far better pieces that Jolivet composed than the Trumpet Concertino (for one, his other trumpet concertante work). Also, the Chant de Linos sounds much better in the version for flute and piano. I won't say it's easy, but it is a nice piece. He also has some piano works which are quite interesting, such as his Cinq Danses Rituelles, which don't seem as awkward as his other works in terms of both writing and the music. I think his bad rap here will be appeased if you just go listen to some of his better works, rather than the ones everyone seems to hate on. His piano concerto, if you can find a copy of it, is also a very good piece.
I have to laugh at this entire thread, because I've played with trumpet players my whole life. I don't think I've met one who has enjoyed playing Jolivet, but they play it, and we pianists receive the full chamber scores...what are we to do with this? On the spot reductions, and ugh. At least Ibert and Franciax (ever played the Flower Clock?) are arranged in semi reductions!Bah! Good thread.
