Last August, Peter Terry, a baritone and musical entrepreneur, co-organized a festival of Spanish Baroque music called Iberica. Over the course of four programs and 10 concerts, a group of local musicians explored a lot of obscure repertoire from areas in Spain, Portugal, and the New World. It gave Boston a dose of substantial music at a time when many high-profile ensembles are dormant or out of town.
This summer, Terry is back with another musical gathering during the dog days. But this time, he has set his sights much higher. The Sons of Liberty Festival opens on Friday and comprises an astonishing 27 concerts over 10 days. The programs cast a wider musical net, with much of the programming focused on American music. Above all, the festival is intended to be an accessible and inviting group of concerts with a kind of openness that fits Boston in the summer.
