What do we make of the complex legacy of Richard Wagner on the 200th anniversary of his birth, Wednesday? Both Performance Today with Fred Child (5-7 PM) and Exploring Music with Bill McGlaughlin (9-10 PM) are exploring the question this week with fascinating results. Tune in tonight to PT, for example, to hear Gabriel Faure's "Souvenirs of Bayreuth" - a cheeky quadrille on themes from the Ring Cycle - as well as Wagner in concert by leading performers (among those on PT this week are Bryn Terfel, Deborah Voigt, Sir Simon Rattle, and Esa-Pekka Salonen).
