Since finishing the Rolling Stones' No Filter tour in July, Mick Jagger has been posting clips of himself working on new music -- which we believe is for the Stones' next album.
His latest post shows him wailing away on harmonica to an upbeat track.
The Stones' last studio album was Blue & Lonesome, a collection of blues covers in 2016. The last album of original material was 2005's A Bigger Bang.
