Question: Which American singer-songwriter known as "the Caruso of Rock", recorded on the Monument Records label and had hits such as "Pretty One," and "Uptown"?
Related documents: [0]  [DOC] Roy Kelton Orbison (April 23, 1936 – December 6, 1988) was an American singer-songwriter known for his distinctive, impassioned voice, complex song structures, and dark emotional ballads. The combination led many critics to describe his music as operatic, nicknaming him "the Caruso of Rock" and "the Big O." Between 1960 and 1964, 22 of his songs placed on the "Billboard" Top 40, including "Only the Lonely" (1960), "Crying" (1961), "In Dreams" (1963), and "Oh, Pretty Woman" (1964). [END] 
[1]  [DOC] Early Orbison is an album recorded by Roy Orbison on the Monument Records label at their studios in Hendersonville, Tennessee and released in 1964. Essentially a compilation of songs from his first two Monument albums, it is most noteworthy for containing "Pretty One", the "B" side of Orbison's second Monument single, "Uptown". Many Orbison fans believe "Pretty One" would have been his first major hit had it been promoted as an "A" side. The second song of interest on this album is "Come Back to Me My Love" which Fred Foster, owner of Monument Records and producer of all of Orbison's earliest hits, says was the song which inspired production of the hit arrangement that later became "Only the Lonely".
