Chicago and Styx at Ball Arena

Two of the best-selling American rock bands of all time on one bill is a hits-from-start-to-finish night, and Chicago and Styx co-headlining Ball Arena gives Denver a deep well of radio standards. The pairing is a draw for multiple generations.

Arena doors typically open 90 minutes before the music. Both bands carry long catalogs, so expect a full evening of recognizable songs.
