Music fans looking for a non-traditional way to celebrate Easter weekend and the beginning of Passover (April 15-17) this year need look no further than the Sarasota Opera House. But it won't be hearing voluptuous voices singing Madama Butterfly. After a two-year disruption in live music, the annual Rites of Spring Festival (RoSFest), now at its 17th edition, returns to Sarasota with an exciting line-up of acts from past and present to satisfy every taste.
