full_context: Document 1: Recorded as Jerry Landis: Recorded as Jerry Landis is a compilation album of music by singer, songwriter, and guitarist Paul Simon, released in 2006. This album contains 18 songs recorded before Simon & Garfunkel released their first album, "Wednesday Morning, 3 A.M.". All songs are by Paul Simon except the song "Beat Love", which is a contemporary recording by Art Garfunkel, recorded under the name "Artie Garr". This album was released six years after an album of Simon & Garfunkel songs, from the same era, that contained a mix of Simon & Garfunkel recordings (under the name "Tom & Jerry"), and Paul Simon and Art Garfunkel songs. He recorded many of the songs on these albums under different aliases, such as "Jerry Landis", "True Taylor" and "Paul Kane".
Document 2: Concepts (album): This sixteen CD set was the first major compilation from an entire era of Sinatra's career.

A departure musically from his earlier work, the album features doo-wop, rock 'n' roll and Puerto Rican rhythms and a number of songs contain explicit lyrics, a first for Simon.
