BEAVER CREEK - The Vilar Performing Arts Center announced two additional shows to its lineup. "An evening of Sit Down with Robin Williams & David Steinberg" will take place at the Vilar on Jan. 17 at 7:30 p.m. Tickets are $225 and go on sale Tuesday at 11 a.m."Robin Williams is a huge accomplishment for us, and illustrates how far the VPAC has come in its 15-year history," said Kris Sabel, executive director for the Vilar Center. "Though we may be only a 530-seat venue, performances of this level reinforce that we are a world-class venue and that with the support of our generous donors and community members, we can bring best-in-class talent to the Vail Valley."Williams, known best for his Academy-Awarding career on the silver screen, takes his infamous repertoire of indelible characters and unparalleled scope of imagination to the Vilar stage for an evening of comedy in sit down format. Williams comes off of a recently wrapped-up "Weapons of Self Destruction" comedy tour, which enjoyed a fully sold out 90-show run.Williams will be joined by comedian David Steinberg. Steinberg has directed numerous episodes of Friends, Seinfeld, Mad About You, Newhart and Designing Women, which he also executive produced. More recently, he directed the hit series Weeds and Curb Your Enthusiasm. His work has earned him several DGA and Emmy awards and nominations."Robin Williams is largely regarded as the funniest man alive, and David Steinberg is the talent behind the greatest comedic sitcoms on television," said Sabel. "To bring these two legends to our stage is an incredible opportunity. Jan. 17 will be a very special evening for us, and one that we'll remember for many seasons to come."Joining the winter lineup is Air Supply, also on sale. Serving as the voice and song of an iconic era of rock across the globe, Russell Hitchcock and Graham Russell come together Feb. 12 for a magical evening of their greatest hits, including "Lost in Love," "All Out of Love," "The One That You Love," "Sweet Dreams" and "Making Love Out Of Nothing At All."
