Catalan duo Tarta Relena (Helena Ros and Marta Torrella) bring an entrancing immediacy to vocal music. Perhaps jokingly, they self-describe their music as “progressive Gregorian”, yet they do traverse the depths of traditional vocal music and elevate their historical inspirations to thrilling and timeless new heights. The result could best be described as an exciting blend between the staggering harmonies of Le Mystère des Voix Bulgares and the cinematic textures of Arca. Debut LP Fiat Lux is a testament to the musical talents of this duo that draw inspiration from Mediterranean folk, Georgian laments and the 12th-century mystic Hildegard von Bingen. The sparse, but gripping use of electronic accompaniment on the album underlines the urgency in Tarta Relena’s exquisite harmonising.

Tarta Relena perform on Saturday 9 April.
