Early June brings the Discover Jazz Festival to Burlington. Friday evening was the street party that opens the event. There were three main stages and innumerable side venues, so the casual wanderer had many options. Music on the street went on for hours. Yesterday featured music in the park, in honor of the late, immensely influential Big Joe Burrell, a fixture on the Burlington music scene for many years. The thunderstorms which have moved through during the past couple of days have been, for the most part, well timed, leaving outdoor events dry. Today we may not fare quite so well, as the day promises to be quite stormy.
