Meyerbeer’s elaborate use of vocal and orchestral forces is seminal in the development of 19th-century opera. Opera Rara’s edition features all the music written for productions the composer supervised. In the opera Adriano, a Knight of Rhodes, comes to Egypt in search of his nephew Armando, whom he believes may have died in battle. In fact he has married Palmide, daughter of the Sultan of Egypt and she has converted to Christianity. The furious Sultan throws everyone in jail, but all is forgiven when Armando intercedes in a plot to overthrow his father-in-law.
