During summer in Chicago there are often so many worthwhile live music events that the Reader can’t fit writeups on all of them in print. I’m using this post to fill out this weekend’s picture a bit. In Thursday’s “Shows to see” post I mentioned the Celebrate Clark Street Festival, which on Saturday is headlined by Malian-French trio SMOD, whose front man is the son of Amadou & Mariam (who roll into town next weekend for Lollapalooza).
