Barcelona is a collaborative studio album recorded by Freddie Mercury from Queen, and operatic soprano Montserrat Caballé. Consisting of semi-operatic melodies with grand production, songs like Barcelona and the Eastern-sounding La Japonaise are startling in their beauty; the two singers from opposite ends of the music spectrum working surprisingly well off each other. The most classically operatic pieces of the project, Ensueno and The Fallen Priest, are alternately gorgeous and powerfully dramatic.
