Since 2001, WTF Jam Sessions has dished up some electrifying live music each Monday covering any number of genres, be they jazz, funk, hip hop, soul, electronica or reggae.

The sessions turn into heaving, frenzied improvisations from featured artists as the night progresses, filled with surprises and off-the-cuff performances that ensure every session is different. Tonight, many of previous guests take the stage for a special anniversary performance.
