A perpetuum mobile-type improvisation played on the 1965 Downes/Walker organ of the Carmelite Priory, London while testing a pair of Oktava MK 012 omni microphones with a Zoom Q8. Best heard through headphones.

Although modest in size, the scheme is exceptionally cohesive and, helped by the Priory's wonderful acoustic, gives the impression of a much larger instrument.
