They've always been a very eclectic festival; when they were in The Hague they had 14 concurrent stages and more than half were definitely jazz of all varieties. I went three times from 1997-2000, and to give an idea of the range of acts, a selected list of what I saw were: Henry Threadgill, Han Bennink in multiple groups, Jeanne Lee with Waldron Trio, Louis Sclavis, Mulgrew Miller & NHOP, Nicholas Payton, Tyner, Joe Henderson, N.G. La Banda, Larry Harlow, Herbie Hancock, Steve Winwood, Buddy Guy, Santana, Youssou N'Dour, Konitz/Haden/Bley, Solal/Peacock/Motian, Earth, Wind & Fire, King Crimson, Jorge Ben, Bobby Previte, Bud Shank, George Coleman, Metropole Orchestra with Konitz... you get the idea...
