At 4 PM Tuesday, go behind the scenes at Iowa Public Radio's studios on the UNI campus for a live taping with wcfsymphony soloist and musical explorer Nadia Sirota. IPR on-air personalities will lead you on a tour of the recently renovated studios, followed by a talk-and-play taping with Nadia (to be broadcast later). Sirota is a leading new music advocate, who next weekend will perform “beautiful music of a higher order than anything else you will hear this year,” with the wcfsymphony. The orchestra's violas will then take center stage in Brahms’ sumptuous (and violin-less) A major Serenade. That concert will be broadcast in the future on IPR's Symphonies of Iowa series.
