Lost is a Wayne Shorter composition that opens the 1979 Blue Note album The Soothsayer, though it was originally recorded in March 1965. The track runs about 7 minutes and 12 seconds and features a strong sextet: Wayne Shorter on tenor sax, Freddie Hubbard on trumpet, James Spaulding on alto sax, McCoy Tyner on piano, Ron Carter on bass, and Tony Williams on drums. The Soothsayer is a post-bop studio album by Shorter, recorded at Van Gelder Studio and produced by Alfred Lion, with five Shorter originals and an arrangement of Sibelius's Valse Triste. Although the session was made in 1965, the album was released in 1979, highlighting Shorter’s edgy, forward-driving style from that period. Lost showcases Shorter’s improvisational approach with modal textures and a propulsive rhythmic drive that characterized mid-1960s post-bop.
