Hoketus was an amplified musical ensemble founded by Dutch composer Louis Andriessen in the Netherlands in 1976.
The ensemble's instrumentation and overall artistic aesthetic was quite radical; it was made up of two equal groups of instruments (two pianos, two Fender Rhodes electric pianos, two sets of panpipes, two saxophones, two electric bass guitars, and two percussionists).
The group had an aesthetic bias toward works that were heavy, loud, dissonant, and brutal, showing influence from both hard rock and the works of Igor Stravinsky (one of Andriessen's favorite composers).
Besides Andriessen, other composers who wrote for Hoketus include Diderik Wagenaar, Cornelis de Bondt, Michael Nyman, Huib Emmer, Klas Torstensson, and Gene Carl.
An ensemble of similar instrumentation called Icebreaker was formed in York, England in 1989, and continues to perform works from the Hoketus repertoire.
