Ba Ba / Ti Ki / Di Do is music Icelanders Sigur Ros have made for 'Split Sides', the last show as of choreographer Merce Cunningham. Radiohead also had also been summoned for the occasion! It's a long improvisational form of 20 minutes, on varied and different instruments (among others: xylophone, music box, dance shoes (), electronic as well as samples of the dancers ... not!) . The atmosphere is very Nordic, sometimes more playful, though almost dark towards the end, but the approach much more experimental.
