The Full Circle Quartet play with a chamber-like intimacy that belies their sinewy strengths. They have an affinity for nature, the English South Downs and its coastlands, creating music that is as affecting as it is timeless. Josephine Davies particularly, has a mermaidian relationship to the sea.

As befits its watery themes, Open Water bubbles up from its sources – the lyrical piano intro of ‘Tributaries’, the fluency of the bass solo that is ‘Flow’ – until it all runs together into the depths of the title track. ‘Weightless’ likewise elicits that gravity defying sensation of floating, which doesn’t stop Davies conjuring a stormy solo. ‘Hirundelle’ meanwhile has a Jarret-like jauntiness that evokes the swoop and dive of swallows and swifts.

Not that all the band’s songs evoke willows aslant a babbling brook: ‘Song for Biko’, with its Township feel is a staunch reminder of the tragedy, personal and social, of Apartheid. There’s also a Township lilt to ‘Evening Sun’ and its reprise of ‘Open Water’. With it comes a sense of release, of play at the end of the day, as Davies dances forth, leaving you wondering where all that music goes after the fade comes in and the tide goes out.
