Recording of Bengt Hambraeus' Doppelroho II. The title indicates that Hambraeus has used as his basic material the range of tones produced by an organ. In this work timbral manipulation becomes a new compositional element. The importance of the organ is immediately established not only in its exclusive use, but as one of the most effective timbral fillers of the gap between live and electronic music.

Recording of Rainer Riehn's Chants de Maldoror.

This work was made almost exclusively with the voice and Microntage.

Commissioned by Chilean pianist Carla Hübner, and premiered by her at the Latin American Music Festival, Bloomington, Indiana, in 1966. In Plectros II the composer extends the idea first explored in his Plectros I - the opposition of two different worlds of sounds. It requires the interpreter to extract "electronic" type of sounds from the piano using both the keyboard and the inside of the piano. No special mallets are required, and the pianist uses fingernails, fingertips or the palm of the hand to obtain harmonics, resonances, and glissandi, or to produce clusters and a variety of different attacks. On the other hand the tape part, produced at the Columbia-Princeton Electronic Music Center in New York, has synthetic sounds - all electronically produced - creating artificial quasi-piano type of sonorities. The goal is to achieve a blending which gives the listener an impression that it is not clear if the sound is coming from the instrument or from the loudspeakers. Plectros II is not a dodecaphonic composition, nor a "prepared piano" one.

Recording of Boguslaw Schaeffer's Symphonie. "Towards the end of 1964, I began work on a large format electronic work. From the beginning, I called it Symphony, not to obey the spirit of contradiction, which is a way of creating a long time out of use, but being convinced that this name is likely to new applications, there especially where it is a matter of simultaneously resonating a sound matter of very disparate origin, thus proceeding by symphonic means. That was our idea of departure. Yet, already in the course of composition, I suffered the magic of the adopted denomination, so that at the end of a certain time I ended up asking myself to write a work of a structure, a format and a symphonic emotional message. Therefore, the essential problem was not to use the electronic language to express only traditional musical ideas, but rather to proceed by truly electronic means without ever going beyond the framework. Moreover, it was a question of rediscovering auditory laws, of developing new means of expression from an electronic mode of thinking and proceeding. Both in its original conception and in its accomplishment, of which a considerable share of merit belongs to Mr. …

Recording of Janez Matičič's Oscillations. This work represents the composer's first electroacoustic composition which was produced as four-channel sound. Motions of sound, specifically from the phenomenon of gravitation, feature prominently in this composition. This work was created using concrete sounds only.
