Earthspan is the tenth album by The Incredible String Band, released in 1972 on Island Records.

It features Mike Heron, Robin Williamson, Licorice McKechnie, and Malcolm Le Maistre.

The core of Robin Williamson and Mike Heron remained intact, but was faltering due to musical indifference.

The band was continuing its exploration into progressive rock and synthesizers in order to create a more commercial-oriented sound.

As a result, the band would lose much of their trademark style that made them popular in the British counterculture of the 1960s.
