Music technology stalwart WALTER SEAR has died in New York, aged 80.
The analogue guru, composer and tuba designer advised Robert Moog during the design of the Moog synthesiser, which revolutionised popular music in the 1960s.
Sear went on to set up the all-analogue Sear Sound studio in Manhattan, New York, where Norah Jones, Steely Dan, Sonic Youth and Lou Reed have recorded.
The studio also became the home of U2 stars Bono and The Edge while they were creating the score for the new Spiderman musical.
