KDWB has announced the lineup for its annual Jingle Ball: Enrique Iglesias, B.o.B.,, 3OH!3, Sara Bareilles, Selena Gomez, Taio Cruz, Mike Posner and the Ready Set. The date is Dec. 6 at Target Center. Are any of these acts ready to perform in an arena? How many of them will feature live musicians? Yes, Jingle Ball is an event that promises that it's sum will be greater than the individual parts combined. Even though many of these stars have had huge hit singles and KDWB DJs will hype this event incessantly, this lineup sounds dubious for an arena. Tickets, priced from $28.75 to $101.30, will go on sale at 10 a.m. Saturday. For more info, go to www.kdwb.com. In other concert news, Broken Bells (Danger Mouse and James Mercer of the Shins) are booked for Dec. 6 at First Avenue. Tickets go on sale at 11 a.m. Friday.
