Europeans Cut In With a New Jazz Sound And Beat
New generation of musicians is emerging from Europe's jazz underground and taking jazz in new direction by melding it with European club-culture styles; musicians, notably from France and Scandanavia, are taking elements from house, techno, drum 'n' bass and jungle scenes and re-establishing jazz's long lost links with popular culture; dubbed European new jazz, this improvisational music is moving out of jazz clubs and into club culture, and young people are willing to line up around block to hear it; photos of Norwegian trumpet player Nils Petter Molvaer, French flutist Malik Mezzadri, Norwegian pianist Bugge Wesseltoft, French saxophonist Julien Lourau and Esbjorn Svensson Trio from Sweden (M)
