Live on stage the Oscar-winning composer’s score is disorientating, ecstatic and strange. Its star, Amanda Seyfried’s pure voice is the anchor in a brief but absorbing set

A few days ago, Amanda Seyfried was on the Graham Norton couch alongside Margot Robbie and Johannes Radebe from Strictly. Tonight, the star of Mean Girls, Les Misérables and Mamma Mia is seated among a rather different set of luminaries: key figures from London’s avant garde jazz scene.

The link here is composer Daniel Blumberg. When he accepted an Oscar last year for his extraordinary score to The Brutalist, Blumberg namechecked Cafe Oto, the leftfield Dalston venue whose improvising musicians have long formed the bedrock of his work. While scoring The Testament of Ann Lee – a biopic starring Seyfried as the founder of the Shaker religious movement – Blumberg was struck by parallels between Shaker worship and free improvisation: a shared ascetic intensity, a cult-like devotion, and moments of wild, euphoric release. The speaking-in-tongues qualities of Shaker devotional singing, he realised, had uncanny echoes in the work of vocal improvisers such as Phil Minton and Maggie Nicols, both of whom feature in the film – and in this performance.
