Next Thursday evening (July 26) at 6:30, Madsen will give a solo recital of harpsichord music from England circa 1700, with works by Henry Purcell, William Croft and Antonio Draghi. Madsen — director of Newton Baroque, the ensemble collaborating with the Bostonian Society on these concerts — will provide commentary throughout the program.

The third and final concert of the series, on Saturday, August 4 at 12:30 p.m., is a program titled "The Mighty Hoboy." That word (from the French hautbois) was an early name for the oboe, and Joyce Alper will perform Baroque sonatas for the instrument from Italy and England, accompanied at the harpsichord by Madsen.

All three of these concerts are free with admission to the Old State House, which is located at 260 Washington Street (corner of State and Congress Streets) in downtown Boston. More information is available at www.bostonhistory.org.
