Gyratory System are one of our favourite groups, constantly perplexing with the treated trumpeting and bizarre live concerts, which feature the evil stare of group leader Dr Andrew Blick, and the prowling antics of his septuagenarian father Robin, who acts onstage like Mark E Smith would if he'd been raised on Miles Davis rather than Philip K Dick and literature. Anyway, their new album New Harmony is out on Angular Records on April 16th, and we've got an exclusive non-album track to give away.

Gyratory System have long been inspired by the landmarks and unloved places of London, with track titles like 'Baron's Court Turret' and 'Sea Containers House'. Now, they get deeper into the fabric of the city with 'The Knowledge', which we assume is named for the training that London cab drivers have to undergo before they get their licence, and then promptly forget where everything is again.
