About this piece

Black Rock Unfolding (2009) is a virtuosic work of about 16 minutes for cello and live electronics by the Belgian composer Luc Brewaeys (1959–2015), commissioned by Guillaume Van Mechelen and written for the cellist Arne Deforce. Its title refers to Brewaeys's ensemble piece Cardhu (2008), Gaelic for "black rock", whose harmonic and rhythmic ideas the cello piece develops further. The linked video is a 2019 performance from the ensemble ChampdAction's Whisky on Stage programme.
