The annual Freihofer’s Jazz Festival is headed into SPAC on Saturday and Sunday, June 27-28, and while the SPAC folks used to be all hush-hush, top-secret, for-your-eyes-only about revealing the schedule of performers, they have apparently come to their senses and loosened up about all that.

Keep in mind that this is not only a festival, but a jazz festival, which means that some things – like the performers and the set times – can change. It’s jazz. Improvise.
