Early music is not for everyone — some of the early Renaissance pieces sound somewhat discordant to our modern ears — but it is fascinating to listen to the early instruments. The Early Interval is great because each of the players is adept at playing multiple instruments — from violin to lute to guitars, from recorders to theorbo to drums and cymbals, which allows them to tackle a wide variety of pieces — and they can sing the a cappella songs, too. And the First Congregational Church, with its vaulted ceilings, is a great setting for a performance.
Columbus is a wonderful town for live music. You just have to look for it.
