The lineup is taking shape for a benefit concert to help victims of the Oct. 1 shooting in Las Vegas in which 58 people were killed and hundreds more injured.

Organizers announced today that the Killers and Imagine Dragons will headline the show, set for Dec. 1 at T-Mobile Arena in Vegas.

Others who are on the bill include Boyz II Men, magician David Copperfield, magicians Penn and Teller, and performers from Cirque du Soleil.

Tickets are set to go on sale Wednesday, priced from $75-$125. Proceeds will go to the Las Vegas Victims Fund.
