Concert events by the Heifetz Institute, Annapolis' own international music festival, reach a crescendo over the next three weekends.

Tomorrow night at the Banneker-Douglass Museum, 84 Franklin St. in Annapolis, institute founder Daniel Heifetz, the Classical Band, and associated string players will present "Music of the Spirits," a program of works by Bach, Beethoven, Tartini, Bruch, Wieniawski, Chausson and Vitali.

On July 23, also at Banneker-Douglass, soprano Carmen Balthrop joins Heifetz and the Classical Band for a program titled "Love and Passion." Works by Mozart, Schubert, Gershwin and Puccini will be performed.

The Final Gala will take place at St. Anne's Episcopal Church in Annapolis on July 30. The highlight will be an unusual version of Vivaldi's much-loved "Four Seasons" with his music and his poetry.

The ticket price for each of these concerts, produced by First Night Annapolis, is $12. Concert time is 8 p.m.
