Released in 1970, Earwax marked the debut album of Dutch Free Jazz ensemble Association P.C., recorded in Wageningen, The Netherlands, and produced by Dutch Jazz pioneer Wim Wigt. The album fuses Free Jazz with Jazz-rock, showcasing an adventurous sound led by drummer Pierre Courbois. The line-up includes guitarist Toto Blanke, bassists Siggi Busch and Peter Krijnen, and Jasper van ‘t Hof on electric piano.

Members Courbois, Blanke and van ‘t Hof are considered as the early inspirators of the Jazz-rock and German Krautrock sound. Now, 55 years later, Earwax by Association P.C., finally sees its first-ever reissue since its original release. This long-awaited edition consists of six tracks and is presented in a gatefold sleeve, featuring details about the musicians involved.
