John Moran will combine three-dimensional art with the sounds of a synthesiser when he presents Annotation at the historic Prince of Wales Opera House at Gulgong.

Twenty-minute sound pieces, interrupted by 30-minute breaks, will accompany artworks displayed on a small forest of white plinths that the exhibition viewers will be able to navigate between.

“All pieces are improvisation on a theme, challenging the moment and venue to inspire the direction of the performance,” Mr Moran said.

“There is no entry fee to the exhibition and performance, creating hopefully a spontaneous and relaxed atmosphere by wandering in and leaving at will.”

The performance will open at 1pm this Saturday, August 12 and run until 8.30 that evening.

Mr Moran said there will be no prices on the artworks, “as to me that can hinder the free spirit of the viewer to relax and just look, observe, think and frown”.

Mr Moran manages art and music therapy for residents, including those with dementia, at St Catherine's, Bathurst.
