Little late for The International Viola Congress to be an Upcoming Event for 2022 (June 1st - 5th), but I hope by posting about it here - people can be aware/prepare for it in the upcoming years.
The International Viola Society alternates the location of their HUGE annual Congress/Festival, so that it's somewhere in North America on even years - some other Continent in odd years. This year's was held in Georgia, USA.
I don't see where they've announced the dates & location for their 48th International Viola Congress in 2023, yet.
