Charanjit Singh is a musician from Mumbai, India, who performed as a session musician, often as a guitarist or synthesizer player, in numerous Bollywood soundtrack orchestras from the 1960s to 1980s, working with filmi composers such as Shankar-Jaikishan, R.D. Burman (Rahul Dev Burman), S.D. Burman, and Laxmikant-Pyarelal. Singh led a wedding band and recorded and released a number of albums covering popular film songs. These were a form of instrumental elevator music, some of which have since been re-released by Sublime Frequencies, such as his steel guitar renditions of "Manje Re" from Bandhe Haath in 1973 and "Chura Liyaa Hai Tumne" from Yaadon Ki Baaraat in 1975. In 1981, he produced synthesizer-based electronic renditions of the Silsila soundtrack in his record Charanjit Singh: Plays Hit Tunes on Synthesizer of Silsila.
Synthesizing: Ten Ragas to a Disco Beat, an album of original electronic disco compositions Singh recorded in 1982, was a commercial failure at the time of its original release, but its re-discovery in 2002 and re-issue in early 2010 garnered attention due to its resemblance to music from the acid house genre of the late 1980s. Since then, certain commentators in the music press have tried to recast Singh as an originator of acid house music. He also used the same drum machine and synthesizers for his experimental electronic calypso record, Experiments in Calypso. His son Raju Singh is also a musician, composing music for films and television shows.
