- Obscure EP, made in Argentina, featuring the electronic and experimental music of Henk Badings. The compositions featured here were first performed during the Holland Festival in 1956.
- This EP, which appeared in the Netherlands with number 400 036 AE, was probably released in early 1958 (or maybe late 1957?). This article from “Het Binnenhof” (Feb. 15, 1958) gives more details.
- Interesting details: the word ‘Minigroove’ has been translated to ‘Microsurco’ and the sentence ‘All Philips records are high fidelity records’ to ‘Todos los discos Philips son de Alta Fidelidad’.
