Picasso and the Avant-Garde--Avenging Angel of the Organ World Cameron Carpenter--Wicked Phila.

Susan Lewis explores the Philadelphia Museum of Art's new exhibition, Picasso and the Avant-Garde in Paris.

Cameron Carpenter fancies himself as the avenging angel of the organ world. He dresses in white - with rhinestones. He plays with a phenomenal technique. And he wants to change everything. David Patrick Stearns looks ahead to his upcoming concert at the Kimmel Center.

And in the latest installation in our Wicked Philadelphia series, Tom Keels explains how the City of Brotherly Love was a hot bed for the "world's oldest profession" during the 18th and 19th centuries.
