Musical and metrical compositions go hand-in-hand in the Vermont Contemporary Music Ensemble’s fifth annual Poetry & Music concert, “What I Mean by Rooted Is Web.” Under artistic direction from Steven Klimowski, the group, committed to showcasing 20th- and 21st-century chamber works, collaborates with Green Mountain State wordsmith Jody Gladding in a unique marriage of melody and meter. The program features electronically modified spoken word alongside music created by bass clarinet, cello, harp and voice in response to Gladding’s verse. “This poetry is impossible to adequately describe,” writes Klimowski in a letter to supporters, “but I find it fascinating and brilliantly effective.”
