WXPN returns to MilkBoy Philly this weekend with its second annual Key Fest. Each bill has been tailored to bring together performances by like-minded local artists for an evening. Kicking things off tonight, you’ll find plenty of hip-hop grooves and electro-soul with Ill Doots, Kate Faust, Hardwork Movement, and Joie Kathos. On Saturday, indie rock/pop-tinged singer-songwriters will be the focus. The Deli Philly’s 2015 runner-up for Emerging Artist(s) of the Year, Kississippi, will be holding down the primetime slot as the evening’s headliner, supported by Shelf Life, Cherry, and Madalean Gauze. And finally, the folkies will be out in Center City this Sunday, and bringing the mellow will be the sweet sounds of Hezekiah Jones, Howlish, Lou, and Friendship. MilkBoy Philly, 1200 Chestnut St., 8pm, $12, 21+ - H.M. Kaufman
