The Budapest-Vienna-Berlin telephone concert, which was held on April 15, 1983, was an extraordinary telecommunication event which took place simultaneously in Vienna (studio of the Österreichische Kultur-Service), Berlin (Auf und Abbau Gallery), and Budapest (Artpool Studio). Artpool got in contact with the organizer of the event, media artist Robert Adrian X, through János Vető. The Artpool Letter published a report on the event (AL 4, 1983).
