The Handel & Haydn Society uses period instruments and techniques in its orchestral and choral performances, yet it's as cutting-edge as any other ensemble in town. Established in 1815, it's the oldest continuously performing arts organization in the country. The company prides itself on its creative programming of "historically informed" concerts, which it stages year-round, with most performances at Symphony Hall and Jordan Hall.

The society was the first American group to perform Handel's Messiah, in 1818, and has made it an annual holiday tradition since 1854 (the 2004 performances will celebrate the 150th anniversary). If you'll be in town in December, check for ticket availability as soon as you start planning your trip.
