Oli Morris and Ollie Grant meet for a rare one off performance of improvised music. Expect explosive rhythms and colourful harmonies all evening.

The duo are familiar faces on the local jazz scene, with Oli having a successful solo career and previously performed with Chrissie Huntley, along with featuring on Emeli Sandé's most recent album.

Ollie Grant is the brains behind Fantastic Stranger, the explosive trio, create an atmosphere rooted in subtly building rhythmic and melodic ideas that can ramp up into a cathartic frenzy.
