Fleet Foxes frontman Robin Pecknold has shared a previously unheard solo track, 'Swimming'.

The low-fi instrumental track 'Swimming' was uploaded to Soundcloud, featuring Neal Morgan on percussion and engineered by Gabe Wax.

A caption with the upload states that it was recorded for brother Sean Pecknold's short film A Study In Time Travel.

Pecknold has taken a break from music over the past few years, returning to his studies at university.

Fleet Foxes' last album Helplessness Blues was released in 2011 but guitarist Christian Wargo recently confirmed that the band will "definitely" return.
