Opening with an apocalyptic, rackety hum, the sophomore album by noted leftfield Londoners Cykada is a trance-like affair in which the beats and riddims of soundsystem culture pull up to the bumper of jazz before reversing back then, pedal to the metal, shooting forward, into a soundscape dappled with influences from West Africa and Eastern Europe and carved with new patterns.

Kafka-esque transformation is at a premium here, evidenced by sleeve notes alluding to the 120dB noise of cicadas and the assertion that when "one cycle ends and silence falls, the next one already begins underground."

And indeed, this sense of swirling menace provides welcome tension through such ominously titled tracks as 'Cracks in the Bricks' (a proper jazz-meets-prog-rock wig out) and 'Last Throes of the Temporal Monolith' (the final gasp of a lost, tripping gamer), as guitars wheel, horns screech, electronics swirl and Tim Doyle's kit drums keep things tight.

There's real beauty here in the quieter, spacier moments, and the head-rush that accompanies the increasingly clashing riffs and reverbs of 'So Divided', a track intended to underline society's need to divide, to posit control as an illusion, feels giddily different. Variously featuring members from Ezra Collective, Maisha and Levitation Orchestra, Metamorphosis is jazz, rubbing its wings together.
