Tomorrow, come to the Swamp for WUStock, a concert put on annually by the Congress of the South 40. Headliner Matt and Kim, an indie band known for their fun and lively shows, will take the stage at 5 p.m. At 2:30 p.m., three students bands will open for Matt and Kim: Rhyme n Reason, Where’s Lionel and the Noam Chomskys. CS40 has been working hard on the event since the beginning of the school year and they expect it to be the biggest WUStock ever. It’s free and open to the Washington University community: no IDs required. It will be a low-key event where you can come and go as you please.

CS40 is really excited to have secured Matt and Kim, a band with three albums under its belt as well as performances at music festivals like Lollapalooza. They released their most recent album, “Sidewalks,” in November, and they’re touring all summer to bring their new songs around the country. They also give a notoriously good live show, as their simple lyrics and pounding drumbeats allow for a sing-and-dance-along romp. The experience of a Matt and Kim show depends largely on the stage presence and antics of the two stars. At Lollapalooza, Kim did a booty dance on the crowd to “Pon de Floor,” and Matt climbed into the rafters. At most of their live shows, they play all of their best and catchiest songs as well as a few covers, including Biz Markie’s “Just a Friend” and Alice DeeJay’s “Better Off Alone.” It should definitely be a WUStock to remember.
