The Round 57

In the fall of 2007, Benjamin Verdoes of Mt St Helens Vietnam Band conceived and composed a five minute classical waltz. “A Waltz for Furnace,” arranged for a string quartet, is led by a rich and robust cello melody, with viola and violin brightly reeling and undulating along with it. It’s a courtly and elegant piece of chamber music, an overtly joyful expression of love. Tonight, following Verdoes’ performance of a selection of brand-new MSHVB songs from the band’s forthcoming record, as well as acoustic performances from buzz band the Globes and Anna Arvan (I Love You Avalanche), “A Waltz,” in its second-only performance, will close the Valentine’s Day Round – fitting, since the piece was originally written as a first anniversary gift for Verdoes’ wife and bandmate, Traci Eggleston. If that doesn’t make your heart dissolve into mush, we don’t know what will. All ages. E. THOMPSON
