Next stop: a cornerstone of the German jazz scene where such greats as Louis Armstrong, Dizzy Gillespie, and Chet Baker once made an appearance. Jazz lovers won’t need to take our word for it—the innumerable photos on display tell musical history. Since 1952, the stage in this rustic cellar has been available for live gigs by old jazz hounds and young talents alike. For diehard fans of this exquisite, home-brewed music, it’s an absolute must.
