The Flexi Disc is a phonograph record made of a thin, flexible vinyl sheet and will deteriorate when played for an extended time. The Flexi’s contain recordings of Van der Mark's father’s last days, reworked into music by Joachim Badenhorst. The edition that comes with the record is the image of a laboratory grown quartz crystal, the artist screen printed at Frans Masereel Centrum. The edition was presented at Kransen, an initiative by Jan Matthé.
