Brecon Jazz Festival this weekend.
Jazz isn't my thing but there are a lot of excellent bands/performers playing a variety of styles of music at fringe events around the town so it should be a fun weekend.
For whatever reason, I can't turn the festival programme into a blue clicky but it can be found on the Brecon Town Of Music facebook page, if anybody wants to take a look:
