the Instant Composers Pool, an organisation which promoted avant garde Dutch jazz performances and recordings, with Han Bennink and Willem Breuker. Mengelberg played with a large variety of musicians. He often performed in a duo with compatriot Bennink, and with other musicians including Derek Bailey, Peter Brötzmann, Evan Parker, Anthony Braxton. Han Bennink (born April 17, 1942) is a jazz drummer, percussionist and multi-instrumentalist. Through the 1960s he drummed with a number of American musicians visiting the Netherlands, including Dexter Gordon, Sonny Rollins and Eric Dolphy. He subsequently became a central figure in the emerging European free improvisation (or free jazz) scene. From the late 1960s he played in a trio with saxophonist Peter Brötzmann and Belgian pianist Fred Van Hove, which became a duo after Van Hove's departure in 1976. Through much of the 1990s he played in Clusone 3 (also known as the Clusone Trio), a trio with saxophonist and clarinetist Michael Moore and cellist Ernst Reijseger. He has often played duos with Mengelberg and collaborated with him alongside other musicians. As well as playing with these long-standing groups, Bennink has performed and recorded solo (such as Tempo Comodo (1982)) and played with many free improvisation and free jazz musicians including Derek Bailey, Conny Bauer, Don Cherry and Alexander von Schlippenbach, as well as more conventional jazz musicians. Willem Breuker (November 4, 1944 – July 23, 2010) was a jazz bandleader, composer, arranger, saxophonist, and bass clarinetist. Since 1974 he led the 10-piece Willem Breuker Kollektief, which performed jazz in a theatrical and often unconventional manner, drawing elements from theater and vaudeville.

The 1980s were for André Hazes and less Koos Alberts. The 1990s were dominated by Marco Borsato. Other well-known names throughout the years were Jan Smit, Frans Bauer, Gerard Joling, Gordon, Guus Meeuwis and René Froger. Another notable Dutch band is Tambourine.
