"The ACMP Worldwide Play-In Weekend is a celebration of the joy of chamber music that occurs the first weekend in March each year. This grassroots campaign encourages people of all ages and abilities to come together and play chamber music for pleasure. ACMP members host play-ins worldwide in creative ways, in groups small and large, informal and structured."
Any forumites doing anything for this? I have requested ACMP UK organizer if they can put me in a group in London.
