Cher

While plenty of the songs Cher played in 2014 at a Quicken Loans Arena show were simply dance floor fodder, the concert had a theatrical dimension to it that never failed to impress (at one point, a veritable circus arrived on stage to entertain the capacity crowd during one of many costume changes). Tonight, Cher rolls into town with Here We Go Again tour. The award-winning singer and actress was recently honored at the Kennedy Center and serves as the co-producer of The Cher Show, a Broadway musical about her life. Her new album, Dancing Queen, serves as a tribute to ABBA. (Jeff Niesel)
