N4 is a brand new jazz quartet, playing "serious" jazz, with tunes from jazz giants as Miles Davis, Kenny Barron, Wayne Shorter, John Scofield, Wes Montgomery, Elvin Jones, but also contemporary music of Cory Wong and Roy Hargrove to mention a few.
Tim Boumen : guitar
William Sassen: tenor sax
Lucien Dirix: acoustic bass & bass guitar
Hans Simons: drums
N4 E- Werk has the same band members, but with a more funky, straight 8th's jazz, fusion-influenced repertoire, although a combination of both; serious jazz & the E-werk repertoire is also possible
