[…] LSP [Laser Sound Performance] is a research trajectory exploring the relationship between sound and three dimensional image by means of laser projection.

[…] Although theoretically all sounds can be seen as sums of multiple sine waves, music in general is often too complex to result in interesting visual patterns. The research of LSP focuses on the subject of composing signals that have both a structural musical quality and a time-based structural visual quality. Different relationships between sound and image are used throughout both the performance and the installation form.

[…] By combining audio with visuals the spatial perception of sound is often being reduced because of the two-dimensional nature of the image versus the three-dimensional nature of sound. With laser(s), it is possible to create three-dimensional changing environments that surround the audience. Here, the image is generated by projecting a laser on a thin layer of smoke or fog. Image and sound originate from the same real-time generated source in the computer. This results in a performance where image and sound play equally important roles. The environment challenges the audience to change their perspective continuously.

[…] In 1962 a group of musicians, mathematicians and electrical engineers gathered at Bell Labs where they composed and recorded one of the first albums of computer generated music called Music From Mathematics. The film 7090 is a graphic response to this historic sound recording.

[…] The commentary by Phil Clark of UbuWeb describes the music on the album as a mixture of strange, other-worldly blips, rushing white noise, tootly reworkings of classical pieces and a marvelous period singing computer version of A Bicycle Made For Two.

[…] The LP Music From Mathematics Played by IBM 7090 Computer and Digital To Sound Transducer was originally released on Decca Records and published by Brunswick (UK) in 1962.

[…] The IBM 7090 was a second-generation transistorized version of the earlier IBM 709 vacuum tube mainframe computers and was designed for „large-scale scientific and technological applications“. The 7090 was the third member of the IBM 700/7000 series scientific computers. The first 7090 installation was in November 1959. In 1960, a typical system sold for $2,900,000 or could be rented for $63,500 a month.
