In februari 2004, Rob Knetsch launched a new music project with the name Knetsch. The goal of this solo project was to create a new kind of experimental music, but it started with a release of two CD's, "What about the past I" and "What about the past II". These CD's contain previously unreleased material and could not be fitted in any of the other projects. On most of the tracks of these first two CD's Rob was accompanied by Paul Rijkens and Jaco Beudeker. In april 2004, Rob released his 150th CD titled "Endless sea". He dedicated this CD to his father, who died in january 2004. The music is inspired by this loss. Also in april 2004, Rob released his first CD with experimental music titled "001". At this time 10 CD's with experimental music are planned.
