This is off-topic and insane, but not to be missed.

The Pin-Barrel Harp is now close to completion and is shown being put through some trial performances by Henry Dagg and Chris Wood, who cover The Long and Winding Road.

The Pin-barrel Harp is a sound-sculpture designed as a public-access acoustic composing machine in honour of Cecil Sharp, it has been commissioned by the English Folk Dance & Song Society and funded by the Big Lottery fund.

Vocals: Chris Wood; arranging/programming: Henry Dagg, who has to wind the machine manually until the motor is fitted.
