Complementary Contrasts / Donaueschinen 2003 is a live album by French turntablist and electronic musician eRikm, released in 2003. Musically it features experimental turntablism and live electronic manipulation, emphasising glitch, noise and electroacoustic textures through improvisation, and it documents a phase in eRikm's career focused on real-time sound processing and the deconstruction of instrumental technique within contemporary experimental music.
