The Republican presidential candidate will be joined by running mate Paul Ryan, Kid Rock and Rodney Atkins for a rally at Red Rocks Amphitheatre Tuesday evening.
The Republican ticket hopes to use the famous concert venue to juice up the GOP faithful as early voting continues in Colorado.
The amphitheater is best known as the setting for the U2 concert film "Under A Blood Red Sky."
President Barack Obama will swing through Denver on Wednesday for an afternoon rally in City Park.
The frenzied campaigning marks the end of the presidential race.
Polls show an essentially deadlocked contest nationally and in Colorado. That means voter enthusiasm and turnout will be pivotal.
This week's events are geared toward galvanizing each side's voters.
