The Forgotten World of EMS

Electronic Music Studios (London) Ltd. was formed in 1969 by Dr. Peter Zinovieff to market innovative ideas arising from his private studio and interest in musical applications of computers. Over the next ten years many seminal products were released and many talented designers worked for the company. EMS had its own peculiar brand of British eccentricity which could be both endearing and annoying, but should be viewed in the context of true pioneering. It is easy to copy and follow others, but not to think up new ideas in the first place and EMS had no shortage of originality. The EMS influence was significant and can be traced into many contemporary products.

The Sound of Analogue Electronic Music in 1979

A clip of David Vorhaus working in his studio in 1979. Vorhaus was also part of White Noise with Delia Derbyshire. This clip contains interesting dialogue about his sequencer MANIAC. 
Regardless, very cool sounds can be heard as well as spotting some EMS gear.

Experimental Sound Artist

A clip from the Shout (1978)
An excellent film staring John Hurt as a sort of Radiophonic Workshop boffin.
Nice shots of him using some EMS gear as well.  Very cool and creepy film, but I was always inspired by the experimental music aspect of it.
