The Colosseum at Caesars Palace in sinful Las Vegas, Nevada. This 4,100-capacity theater located in the heart of the Vegas Strip is a well-known concert and show venue. However, it is without a doubt best known for the creative, perhaps over-the-top residencies that it produces, bringing top-tier artists and bands to Las Vegas for extended periods of time. Canada’s top songstress Celine Dion sets the standard with her A New Day residency that opened the venue back in 2003 and lasted a full four years – until the end of 2007! Musicians crossing all genres have done the same, on a lesser scale, including Elton John, Shania Twain, Cher, Rod Stewart, and in recent years, Stevie Nicks, Mariah Carey, and others.
