After a much-needed renovation, this legendary jazz club is back anchoring the prestigious end of Poznań's live music scene. While it seems every city in Poland has a jazz venue named after the famous American record label, Poznań's Blue Note is the real deal, hosting thousands of esteemed international touring musicians throughout its over-25-year lifespan. Located in the former boiler rooms of the Imperial Castle, Blue Note presides over 400m of cellars, painstakingly adapted into an acoustic space so pristine it has been used to record several concert albums and videos. The club's 'Jazz Top' series brings big brand-name jazz players to Poznań, but funk, blues and soul, as well as hip-hop, r'n'b and DJ nights also appear on the docket. Check their sites to see what's on the calendar; when there is no event, the space is typically closed.
