There's a whole scene happening, much coming out of London. My 16 year old son has turned me on to several new artists.
If you ever have an opportunity to see Sons of Kemet, do so. They are great live. Combining elements of Avant garde jazz, tribal rhythms and punk-rock energy they will amazing you with what is possible from a Sax, Tuba and two drummers.
Much of this new wave of jazz is also incorporating elements of hip-hop and rap which really is consistent with the development of jazz through the years.
