Liquid Acrobat as Regards the Air
 Liquid Acrobat as Regards the Air is the ninth album by the Incredible String Band. It features Mike Heron Robin Williamson Licorice McKechnie and Malcolm Le Maistre. The album was the band's first almost entirely electric recording; a new feature that was to define the change in the band's sound throughout their final period through 1974. The album did well on the charts and was the most financially successful of the band's output.[citation needed]
