Take a look at the cover of this week’s B Side reproduced directly to the left of these words and you will immediately notice two things: 1) that it’s once again time for the massive Chicago Jazz Festival (which started today at noon), and 2) that for I don’t know how many years running the Reader isn’t advertising our equally massive guide to the festival with the slogan “Jazzed for Jazz Fest,” which I have no idea why not. If 49 sets in four days isn’t enough jazz for you we’ve got a comprehensive guide to the many afterfest jam sessions happening over the weekend.
