Audible Edge 2021’s program has literally something for everyone – or at least, everyone with a penchant for the strange and wonderful. Between April 6 and 18, the festival invites you to monolithic performances within a surround sound speaker array, basement shows traversing experimental theatre, avant-garde metal and free jazz, oddball parties and folk shows, and that’s not even half of it. You will love some of it. You will find some of it confusing. So will we. This is good!
