This Memorial Day weekend, May 28 through 30, the second Windy City Sound Clash takes over Subterranean with four shows of punk rock, pop punk, and rock 'n' roll featuring 28 local and national acts. Toys That Kill headline Friday's show, which begins at 7 PM, and the seven other acts on the bill include Dave Merriman of the Arrivals, Mikey Erg, and Dude Jams. There are two concerts on Saturday: an all-ages show at 4 PM with the Ataris, Banner Pilot, and the Menzingers and a 9:15 PM show headlined by the almighty Mushuganas, playing another of their extremely sporadic reunion gigs to celebrate the release of the "retrospective" album Lows in the Mid 90's (Beercan). The festival wraps up Sunday with a 6 PM show that includes sets by the Teen Idols, the Dopamines, Be My Doppelganger, and the Jetty Boys. Four-show passes cost $38; tickets to individual shows range from $8 to $15, depending on the day and whether you buy in advance. Aside from Saturday's early all-ages show, every event is 17+.
