Jelly Roll Morton "Black Bottom Stomp"

This song makes me imagine an energetic jazz band playing on a stage in a densely filled room of partygoers in Gatsby's mansion, overlooking a wide sea of both dancing and mingling people. The music would give the room a permeating feel of lightheartedness and energy. The mood is upbeat and energized, which is why I envision people laughing, dancing, and drinking as it plays.
