Semper Liber (feat. Anna von Hausswolff, Claire M Singer, Mike Harding, Marcus Davidson, Maia Urstad, Charles Matthews & Hildur Gudnadottir)

'Semper Liber' consists of a series of duets featuring Marcus Davidson, Hildur Gudnadottir, Mike Harding, Charles Matthews, Clare M Singer, Maia Urstad and Anna von Hausswolff and are drawn from recordings made at Spire events since 2009. Mixed by its curator, Mike Harding, at the Völlhaus, and mastered by Mark Van Hoen, this powerful 4 track collection - to be played as one piece - explores the sonics of the mighty organ in all its thundering glory.

The 4 colour plates by the art historian and author Sydney Russell show cave art from 4 to 6 thousand years ago. Taken in Brazil on one of several expeditions she made around the world, these highly emotional works reveal the sophistication and ageless quality of the imagination of the peoples who were expressing themselves at this time; they have been slow to reveal their beauty to us, having survived all weathers; their acoustic soundtrack unfolds slowly, submersive and involving.

Sydney Russell writes: "These photographs were taken in 1976 in Brazil. We eventually obtained minimum radio carbon datings for levels covering the paintings from approximately 3750-2500 BCE. They originate from the rock shelter sites of Sucupira, (Lagoa Santa) and Lapa do Cipo (Santana do Riacho), near Minas Gerais and Quadrillas (Montalvania), Bahia.
