Tune in tonight at 7 as Marin Alsop conducts the Los Angeles Philharmonic in Tchaikovsky's last symphony, a heartfelt emotional journey known as the "Pathetique," and in a beautiful work by the Argentine composer Osvaldo Golijov, Azul. Composed for Yo-Yo Ma, Azul is now being performed by other cellists, including the soloist in this concert, Joshua Roman.
