The Aragon Ballroom is the name of two historic ballrooms. One, still in operation, is located in Chicago, Illinois. Chicago's Aragon Ballroom, located on West Lawrence Avenue approximately five miles north of downtown in the Entertainment District area known as Uptown, Chicago, was built in 1926. The Aragon Ballrom's proximity to Chicago's "el" trains helped people flock to the hall, and crowds often exceeded 18,000 guests over the six open nights each week. The Aragon Ballroom hosted nearly all of the top names of the big band era. Among the best known names were Frank Sinatra, Tommy Dorsey, Xavier Cugat, Glenn Miller, Lawrence Welk, Guy Lombardo, Dick Jurgens, Harry James, Kay Kyser, Benny Goodman, Sammy Kaye, Artie Shaw, Eddy Howard, Duke Ellington, Jimmy Dorsey, Wayne King, and many others. In 1973, Latin promoters Willy Miranda and Jose Palomar became owners of the Aragon Ballroom. Today, the Aragon Ballroom under the name Aragon Entertainment Center, the hall hosts a variety of Spanish language shows as well as English language rock concerts. Recent rock acts include the Black Eyed Peas, Muse, Slayer, and 2 nights of Umphrey's McGee on December 30th and 31st, 2005.
