Trumpeter
Dave Douglas and a slew of artists associated with him, such as pianist
Uri Caine , bassist
Mark Dresser and pianist
Vijay Iyer should definitely be checked out. All are pushing the boundaries of improvised music in various ways. Hopefully you'll give them a try as I expect you'll make some wonderful discoveries. Many of them have links pages where you'll find names of even more artists who are all creating amazing new things.
Good luck.
