On Sunday, April 29, Germany's Heidelberger Frühling festival presents its first live video stream, offering a program of opera highlights from two world-class singers: baritone Thomas Hampson and bass-baritone Luca Pisaroni. Accompanied by the WDR Rundfunkorchester under Massimo Zanetti, they will perform to a sold-out audience; the concert marks the last night of the 16th Heidelberger Frühling, which has -- since its opening on March 23 -- been showcasing internationally renowned artists in the picturesque setting of the city known as "the cradle of German Romanticism." The April 29 live stream, sponsored by the German consulting firm MLP, will be available free of charge on www.thomashampson.com, www.lucapisaroni.com, and www.mlp-heidelberger-fruehling.de at 12 noon EDT (6 pm CET). The stream will also be available on demand until May 6. Meanwhile, New Yorkers can watch Hampson in an interview with Paula Zahn when he is profiled on THIRTEEN's NYC-ARTS show, to be broadcast tonight at 8 pm EDT; fans outside the New York area can see the segment online at www.nyc-arts.org.
