The biggest pop radio station in the nation, Z100 (a.k.a. New York’s WHTZ, 100.3 FM), is supporting Do Something by making us a part of their summer concert extravaganza, Zootopia. The lineup for this mega event on May 17 is a Who’s Who of 2008 pop, from headliner Miley Cyrus (seen below as her alter-ego, Hannah Montana) to Jonas Brothers, American Idol champ Jordin Sparks, One Republic, Simple Plan, Sara Bareilles, Gavin DeGraw--and for your older sibs and parents: the first reunion gig for ‘Nsync and Backstreet Boys forerunners New Kids on the Block.

Though the show’s already a sell-out, those seeking free ducats are invited to come to the pre-show festivities at Zvillage in the Izod Center’s parking lot, where there will be opportunities to win a pair. Also on deck: free performances from Bareilles, Flyleaf and Miley Cyrus’s brother’s band, Metro Station, autograph sessions from some of Zootopia’s stars – and several Do Something stations promoting voter registration and awareness for a variety of causes.
