Chicago es, junto con Blood, Sweat & Tears (BS&T), la banda más representativa,1 y la más exitosa en términos comerciales,2 de lo que se dieron en llamar Big Bands de Rock. Se fundó en la ciudad de su mismo nombre, en 1967, aunque inicialmente se denominó "Chicago Transit Authority", nombre que debieron recortar por problemas jurídicos con la autoridad de transporte público de la ciudad. El grupo permanece activo en la actualidad.
