The SalMar Construction is an amazing large music synthesis engine conceived and constructed in the early 1970's by a composer for use by a composer. These unreleased recordings were made at IRCAM in Paris in 1983. It illustrates the power that an electronic composition can achieve when the composer arrives at a true synergy with his synthesizer. This LP represents a significant performance by Salvatore Martirano (1927-1995) on his unique instrument, the SalMar Construction. Under development from the late 1960s, the SalMar is believed to be the first interactive 'composing machine' with digital logic circuits at its heart. The performance took place in the spring of 1983 at the Institut de Recherche et Coordination Acoustique/Musique (IRCAM) in Paris. It illustrates the power that an electronic composition can achieve when the composer arrives at a true synergy with his synthesizer.When you listen to this recorded performance of Sal Martirano playing his 'Construction,' you experience such mastery. The instrument under his command does his bidding, and what you hear are compositions, not jams.
