You think you have unsual tastes?
Check out Max Raabe, one of my absolute favorites. Max is a German baritone who, with his Palast Orchester, recreates German dance, film, and cabaret music of the 1920s and 1930s. If the flowering of Weimar-era film, music, theatre and art before the Nazi onslaught interests you, you must get to know Max.
Max is other-worldly, hilarious in a dry, mischeivous way, and a really great singer. The Palast Orchester musicians are incredible.
