Spur of the Moment is an album of experimental music by Peter Hammill and Guy Evans, originally released as cassette tape on the Red Hot label. A remastered version was released on CD on the DaTE label in February 1988 (not in 1991, as Sofa Sound suggests). The album is currently out of print.Hammill plays the grand piano, guitar and keyboards driving samplers and synthesizers, and Evans plays acoustic and electronic drumkits.

All songs that evening were played in varying line-ups...
