An explosion of creativity reverberates across town at the Cabot Arts and Music Festival. The grooves debut on Friday evening with a show by Pointe Noir Cajun Band and continue on Saturday with 12 bands across four stages. Artist Lars Hasselblad Torres oversees a community collage project that might get merrily messy, Modern Times Theater and Corrugated Spectacles bring the puppets and the laughs, Tim Jennings captivates with Vermont stories, and Oscar Scanlon fiddles for contra dancers.
