This classic minimal music album is now available again on vinyl for the first time since the 70s. Californian composer Terry Riley’s In C, first issued on vinyl in 1968, is widely acknowledged as a Minimalist landmark that altered the course of twentieth-century music. His influential album A Rainbow In Curved Air, which appeared the following year, is a vivid fusion of rock and raga, jazz and psychedelia realised through overdubbing on an 8-track machine which had recently been installed at the studios of Columbia Records.
