A Vintage Introduction to the Mellotron
By James Grahame
The Mellotron is a tape sample playback keyboard from the 1960s that made an appearance on multiple Beatles albums, among others. Each key triggers a magnetic tape strip that runs for a maximum of 8 seconds, making it into a tremendously complicated version of a modern digital sampler. This British Pathé film is a wonderfully daft time capsule from 1965 that's definitely worth watching.
