I was in Gateshead and Newcastle last week and nipped into the wonderful Baltic Centre. From the gallery at the top of the building you can gaze over the regeneration of the River Tyne docks and watch the amazing new swing bridge rise and fall to let tall ships pass. The gallery was showing an intriguing collection of work by Cornelia Parker (including a great installation of suspended squashed brass instruments) as well as esoteric paintings by American composer and artist John Cage.
