The Lost Tapes is a compilation album by American rapper Nas, released September 23, 2002, on Ill Will Records and Columbia Records. It follows his artistic comeback in 2001, which led to his record label's release of the album. The album compiles previously unreleased tracks that were discarded from recording sessions for Nas' previous studio albums, I Am... (1999) and Stillmatic (2001). The songs feature production by L.E.S., The Alchemist, Poke and Tone, Precision, and Deric D-Dot Angelettie, among others. The Lost Tapes features a low-key, sparse sound and themes regarding sociology and urban life. Music writers have noted the album for its nostalgic tone, austere production, and Nas' detailed narratives.
