Am Olympiapark 1, München
Classical evening in BMW Welt, with violin and piano. From the site: "On 26 October, Classic & Lounge at BMW Welt gives you the opportunity to experience two extraordinary musicians live: the multiple-award-winning American violinist Hilary Hahn and the German sound artist Hauschka, who will be jointly presenting their unusual improvisation opus, entitled “Silfra”. Named after an Icelandic natural phenomenon, “Silfra”, with its improvisation of classical and electronic music, is an exclusive musical event that will long stay in your memory."
This is not for free, you have to buy the tickets yourself :)
