With a career spanning four decades, 33 albums — three of which are Grammy winners — Robert Spano conducts the Louisville Orchestra this week for one night at Whitney Hall on Saturday. In this conversation, Spano reflects on conducting music by all of his childhood idols, like Stockhausen, Boulez, and Lutosławski; how "new music" has shifted from an academic, binary choice for composers to anything-goes; and a few dream projects he still has in his bucket list.

My guest for the Concert Talk (6:15pm in Whitney Hall) is composer Christopher Theofanidis, whose work On the Bridge of the Eternal starts the concert, followed by Claude Baker's The Glass Bead Game (commissioned by the LO), and Sergei Rachmaninoff's Piano Concerto No. 3 with pianist Tony Siqi Yun.
