Souvenir is a composition by Mark Sandman, recorded by Morphine for their album The Night, which was released posthumously in 2000 following Sandman's death on stage in July 1999. The song reflects the introspective, emotionally charged character of much of Sandman's late writing, with lyrics that meditate on memory, attachment, and the objects and impressions people carry with them from past experiences. The arrangement follows Morphine's established format of two-string slide bass, saxophone, and drums, a stripped-down configuration that the band used to create music of surprising depth and variety. Dana Colley's tenor saxophone plays a central role in the piece, functioning as both a melodic counterpart to Sandman's low, spoken-sung vocal style and as a soloing instrument that stretches out within the song's framework. The absence of guitar or keyboards, a hallmark of Morphine's approach, places particular emphasis on the interplay between bass and saxophone, with each instrument occupying its own register while creating a full, immersive sound. Souvenir captures the band at a point of artistic maturity, demonstrating how effectively their unconventional instrumentation could convey emotional nuance. As part of The Night, the track carries additional weight as one of the final recordings Sandman made before his untimely passing at age forty-six.
