For the past three UMS seasons, Scott Hanoian, Music Director of the UMS Choral Union, in conjunction with the annual Handel’s Messiah performances, has presented a pre-performance talk about the Saturday evening concert. He again will give a conductor’s inside-look at Handel’s treatment of Charles Jennens’ libretto. Mr. Hanoian will be joined by local soloists to bring insight through illustration of the music and text.
