Kendrick Lamar and Stevie Wonder are headlining the 2015 Life Is Beautiful festival (September 25 – 27), which is already a great reason to book your ticket to Las Vegas. Today, the festival announced that Chance the Rapper is joining the fun. Kendrick and Chance teamed up recently at Bonnaroo to form a funk-rap dream-team with Earth, Wind & Fire. With the two MCs appearing at another event, who knows what could happen? A new version of Chance's Arthur theme, "Wonderful Everyday," would certainly be appropriate.
