Here are three hey-it’s-only-Wednesday-but-let’s-get-the-new-year’s-weekend-started-early reasons to get out and see an Umphrey’s McGee “hump day” show at the Riviera Theatre... 1. Tonight marks the start of the band’s eleventh straight year of New Year’s Eve shows in the fair city of Chicago that they have long called home, dating all the way back to 2000 at the Cubby Bear. They’re back at the Riv for this run for the first time since 2004. They’ve shown Chicago love, now it’s your chance to give it back. 2. There’s no opener (or in band parlance: “Nopener”) tonight, or at all during the run. Not that years past haven’t boasted some stellar support from the likes of Taj Mahal and Tortoise among many others, but sometimes you just want and need pure, unadulterated and uninterrupted Umph. So that means get there early even if you have to stand in a line all the way to the Aragon. 3. Along with heading back to the Riviera they are also repeating a move they made in 2004 by filming all three nights for an upcoming DVD release. That means if you do get stuck in a slow moving line as power tripping security guards do their best TSA operator impressions, or have a little too much liquid refreshments to recall the encore, the band will be providing an HD audio/visual record of the night to help fill in any missing gaps. 7:00 p.m. Wednesday, 12/29. Riviera Theatre. SOLD OUT.
