"Spring" is a song by Lupe Fiasco, released as the 16th and final track from his fifth studio album, Tetsuo & Youth (2015). Along with being the last of the four seasons in chronology, this instrumental depicts joyfulness with the sound of nature and children, possibly symbolizing youth and renewal. The title can also mean "upwards" and how, like seasons that cycle, the listener repeats the order (in this case, reverse).
The violin was played by Rosy Timms, a Berklee student.
