When »Sonne = Blackbox« was first released in 2011, three years had passed since the world first learned of Ursula Bogner's work. Since then, her identity had been surrounded by rumours, her graphic work have been exhibited (CEACC, Strasbourg, France, 2011 and elsewhere) and her compositional instructions have been performed (by Mo Loschelder, Andrew Pekler, Kassian Troyer, Jan Jelinek among others). The music of »Sonne = Blackbox« was compiled by Andrew Pekler, the album presents Bogner's early experiments with voice and tape music – a previously unknown emotional side of her music is revealed here through her singing.
