Boléro. A stately circular dance to a piece of music with two standards that repeat itself like a perpetual motion machine. In a rhythm that puts you in a trance. Gently at first but increasing in volume, again and again. That is the feeling with this glass sculpture that Rineke therefore calls Boléro. One size lighter blue, the other darker, full of blue glow, brilliantly fused glass that seems frozen in an epoxy pedestal.
