Postmodern Jukebox, also widely known by the acronym PMJ, is a rotating musical collective founded by arranger and pianist Scott Bradlee in 2011. PMJ is known for reworking popular modern music into different vintage genres, especially early 20th century forms such as swing and jazz. Postmodern Jukebox has amassed over 1.4 billion YouTube views and 5 million subscribers.

Each week, Postmodern Jukebox releases a new video on YouTube. Although originally most were filmed casually in Bradlee's living room, sets became more elaborate over time. The band has covered songs by artists ranging from Lady Gaga and The Strokes to Katy Perry and the White Stripes. Since their beginnings as a small group of friends making music in a basement in Queens, New York, Postmodern Jukebox has gone on to feature 70 different performers and tour six continents.
