I just have to chime in here. I live in Norway, and in the last 30 years some very, very interesting music which can be called jazz been created in Scandinavia especially. The 70s brought the record company ECM. This company (or the man behind it Manfred Eicher), has put out some amazing jazz (amongst other things). Some artists from this period is Jan Garbarek, Terje Rypdal, Bobo Stenson, Jon Christensen, Arild Andersen and of course Keith Jarrett.
During the 90s both the acoustic and the electric jazz scene grew, especially in Norway. Bugge Wesseltoft used a jazz approach towards electronica, and combined the club music (he used DJs in his recordings and live) with jazz. Very successful to my ears. In the late 90s a band called Supersilent released it's first album. Combining noise, trumpet, voice and keyboards they created frightening and very fascinating music. All the music was and still is purely improvised. The acoustic scene grew aswell, still with a strong attachment to ECM. Artists like Trygve Seim developed the "sound" created by Jan Garbared and changed it into something different. Check out the his last CD Sangam. Also check out the Tord Gustavsen Trio. Another great trio, with great success is the another piano trio; e.s.t. This group is swedish.
The more free-jazz scene grew at the end of the 90s. Lots, lots of duo and trio constellations were created, and made intereseting music. Not "easy" music, though, but imo highly fascinating. Some names/bands: Paal Nilssen-Love, Mats Gustafsson (which recently released an album with Sonic Youth), Ingar Zach, Atomic, The Thing. Especially interesting is the duo record between the norwegian drummer Paal Nilssen-Love and the american saxophonist Ken Vandermark.
I don't know how hard it is to get hold of these records in the US, but I would think that the ECM-catalog should be possible to get.
