John Havermans - Garden Pt 1 and Pt 2 (two tapes, De Fabriek Records & Tapes, 1983)
Many of the releases on De Fabriek Records and Tapes are by the band De Fabriek, but some are by others, mostly Technological Aquiver (or TLA, or The Lost Attick), but there are also two volumes of 'Garden' by one John Havermans. I have no idea who he is, except that he contributed to De Fabriek's 'Neveleiland' record. On Garden Volume Pt 1 it says all music is recorded by a Moog synthesizer. Garden Volume Pt 2 has no info.
