Atrium, Danish cellist and composer Josefine Opsahl's (b. 1992) debut for Dacapo Records, is a strikingly original statement, focusing on her own music. The title has two definitions: one biological, one architectural. Out of their collision, Opsahl draws a reverberating series of dualities: soft/hard, organic/manufactured, natural/cultural. These are expressed most fundamentally in her distinctive instrumental set-up of cello and live electronics, which allows her to build entire orchestras of electronically modified and duplicated cellos live and in response to her acoustic playing.
