I'm agreed. My view from listening to his last three albums is that he is a talented trumpeter in a more traditional vein, but that he gets let down by his ideas.
I thought that the rapping and syrupy strings on Origami Harvest in particular were just embarrassing: stale and out of date, and seemingly aimed at the kind of music that a "cool aunt" is into. Guardian music pages / Mercury award stuff. It brought back bad memories of Soweto Kinch from my younger days.
(and that's before you get into the rapper in question...).
There's such a strong crop of younger jazz musicians with strong sounds and fresher ideas (whether of the sort that Steve Reynolds mentions, who I love and who really do have fresh ideas, or at the more mainstream end) at the moment that I don't really understand why he gets so much bandwidth.
