WGCI's Big Jam

( November 15, 2012 )

WGCI's Big Jam will feature many of the top R&B and rap artists listeners hear daily on the Clear Channel station. Headlining the show will be rapper Rick Ross, with Keyshia Cole, Wale, Future, Fat Joe and Kelly Rowland also performing.

Why go: The promo for the Jam says there will be a "special cameo appearance" by Usher; a hologram or video stream of the pop and R&B singer with Michael Jackson-like dance moves is worth a ticket.

Reconsider: You can't come up with a handful of favorite songs from the lineup.

7 p.m. Friday at Allstate Arena, 6920 N. Mannheim Road, Rosemont; $55-$150; 800-745-3000, ticketmaster.com
