In just one week, Denver's Mission Ballroom will have its grand opening night with Colorado's The Lumineers headlining, but you can take a sneak peek inside before the doors open to the public. 

It's been years in the making, but the new venue in RiNo, a 60,000 square-foot one at that, will be open on Wednesday, August 7. Mission Ballroom will seat around 3,500 and has a moving stage.

Outside, you'll see the large warehouse-esque building...

....but on the inside, you'll find something more colorful.

Not to mention it's equipped with a huge disco ball.

Dozens of acts are booked between now and the end of 2019, including classic artists like Steve Miller Band, Collective Soul and Morissey, country artists like Midland, rockers like Social Distortion, and modern artists like Bastille, Of Monsters and Men, X Ambassadors and Ludacris.
