Aspiring and seasoned performers combine feisty fiddles and fleet feet in a display of multicultural heritage at the Young Tradition Festival, a weekend of all-ages activities hosted by Vermont Folklife. Friday evening’s community dance party at Burlington City Hall Auditorium invites neighbors to cut loose with participatory choreography taught by local artists. Saturday kicks off at the farmers market with a student-mentor showcase featuring a cornucopia of global rhythms and unique instruments, followed by a family jam sesh at the SEABA Center. The day concludes back at the auditorium with a concert headlined by acoustic duo Alex Kehler and Nicholas Williams.
