In 1957, Kid Baltan (Dick Raaymakers) and Tom Dissevelt released their debut album, "Song Of The Second Moon", recorded at the Philips studio in the Netherlands. The public remained interested in the new sounds being created around the world, as can be deduced by the inclusion of Varèse's "Poème électronique", which was played over four hundred loudspeakers at the Philips Pavilion of the 1958 Brussels World Fair. That same year, Mauricio Kagel, an Argentine composer, composed "Transición II". The work was realized at the WDR studio in Cologne. Two musicians performed on the piano, one in the traditional manner, the other playing on the strings, frame, and case. Two other performers used tape to unite the presentation of live sounds with the future of prerecorded materials from later on and its past of recordings made earlier in the performance.
