Do you mean bands and outside performances/events? If so, then there’s a group of students called the Program Activity Council (PAC), which is an on-campus job (paid) that organizes events. They work with Student Life to bring bands, comedy shows, and other events to campus.
I think students are very involved. Some people even bring events to Bennington without PAC. Friends of students who have bands often come to visit and perform in student houses just for fun. We just have to make sure someone at the school knows they’re coming, but it’s really a simple process.
Hope that helps!
