Three Chord Theatre was one of Sonic Boom’s two open performance nights in the city of Glasgow and was held weekly in the Flying Duck basement. It saw performers of all types visit to perform in a safe and supportive environment that focused on community and mutual respect above all else. Performers included actors, magicians, musicians, dancers, singers, storytellers, theatre groups, avant garde theatre troops, poets, and many many others. It ran every weekend from 2010 until 2014
