Scott Bradlee's Postmodern Jukebox (PMJ) formed in 2011 when pianist and arranger Scott Bradlee began reinterpreting modern pop songs in vintage styles, drawing from his early interest in jazz and Motown records. Starting as YouTube videos recorded in Bradlee's living room, the project gained traction online, amassing over 3.5 million subscribers and more than one billion views on its channel. Collaborations with vocalists such as Casey Abrams, Haley Reinhart, and Noah Guthrie helped expand its reach. PMJ's musical style fuses contemporary hits with pre-1980s sounds, including 1920s swing, jazz, ragtime, and Motown rhythms, performed live by rotating musicians and singers. Notable releases include Bradlee's book Outside the Jukebox, detailing the project's origins, and annual talent contests that feature winners in videos and tours. The group transitioned to live performances, evolving from small Northeast and West Coast tours to larger global venues, often structured as variety shows without Bradlee at the piano in recent years. PMJ remains known for its immersive, era-blending live shows.
