Allegro Baroque and Beyond closes its mainstage series Friday at the Bing Crosby Theater with “Viva L’Italia,” a program of Italian baroque music performed on period instruments.

August Denhard of Seattle will perform two solos on the theorbo, a long-necked lute with an extended bass range.

Other instrumentalists include Peter Cama-Lekx and Joey O’Donnell on baroque violin, Barbara Krumdieck on baroque cello and Allegro co-artistic director Beverly Biggs on harpsichord.

Seattle soprano Rebekah Gilmore, a soloist in last season’s Allegro performance of Handel’s “Messiah,” will be featured in motets by Merula and Vivaldi.

The concert begins at 8 p.m. at the theater, 901 W. Sprague Ave. Tickets range from $18 to $25, by calling (509) 455-6865 or online at www.allegrobaroque.org.

Eastern Washington University music professor Jane Ellsworth will give a pre-concert talk at 7:15 p.m.
