This week's show is a premiere of sorts. Our guest Gabriela Imreh is an outstanding pianist, and she and her husband, conductor Daniel Spalding are detectives as well. Imreh shares the fascinating story of their precious discovery--Vittorio Giannini's Piano Concerto, a major work that she went on to record. The Concerto had almost been forgotten since its first performance in 1937; Imreh and her husband brought it back to life. Hear their story on this week's Crossover.
