FOLK AT THE FOUNDLING: Spiro + Eska

Dazzlingly good Bristol-based instrumental quartet play the second of three concerts placing top folk musicians in the poignant environs of the Foundling Museum, where they'll perform in the beautiful Picture Gallery. Spiro's gyroscopic sound (the band name and the title of their acclaimed 2012 album, 'Kaleidophonica', are no accident) swirls guitar, mandolin, violin and accordion lines into euphoric yet technically rigorous folk dances inspired as much by minimalist classical music, and punk, as by folk. Excellent Zimbabwe-born vocalist and composer Eska, who's worked with Nitin Sawhney and Tony Allen, delivers equally detailed folk-soul in support.
