Schtinter produced the first ever release of Frans Zwartjes' music, released in May 2014 (vinyl re-issue late 2014):

An album comprised solely of never-before heard music composed and recorded by Frans Zwartjes between 1966 and 1999. Signed by the artist, the album is available in an edition of 50 cassette tapes, designed by Traven T Croves with paintings and photographs by Frans. Each includes two prints of unseen photographs by Zwartjes, with screen printed insert and case.
