FRANS ZWARTJES studio remains untouched since his passing in 2017. In early 2023, we returned to the studio and discovered a trunk of unlabelled 3/4 inch tapes, containing completely unheard music by ZWARTJES. These works, largely synthesiser-based improvisations for films either unmade or unfinished, were played and recorded by ZWARTJES between the late 1960s, through his most fertile filmmaking period in the 1970s, and continuing in to the early 1980s. Unlike his previous releases, these recordings have been transferred directly from the original source tapes, newly mastered and available to hear for the first time as a double LP release. A comprehensive new interview with TRIX ZWARTJES, the life-partner and collaborator of FRANS is included in a booklet accompanying every copy of the record.
