This week's B Side cover is an insightful feature on rapper Big Sean, whose mouth's been writing a lot of checks that he's hoping his sales figures will cash. Three Beats shares news of challenging cassette labels, geographically scattered experimental-music troupes, and earnest Italian documentary makers. Artist on Artist matches up prolific local underground auteur Peven Everett with Tortoise guitarist and jazzer-about-town Jeff Parker. In In Rotation I laud the genius of Badfinger, local rock videographer John Yingling stumps for Lechuguillas, and noisenik Rotten Milk shares his love for Yolanda Be Cool's brilliantly annoying "Pa Parla Americano." On the Soundboard we talk upcoming shows by Thee Oh Sees, Gillian Welch, Bon Iver, Cass McCombs, Smart Bar's Juke Fest 2011, and more. And if you didn't get enough standing around outside watching bands last weekend, our guide to Wicker Park Fest, featuring Wild Flag and Wavves, might help you do so this weekend.
