With their shaggy corn-silk hair and seafarer beards, the strapping members of the Danish String Quartet could be mistaken for 21st-century Vikings. But unlike their marauding forebears, this supremely gifted group of thirtysomething Scandinavians—three Danes who met as schoolboys and a Norwegian cellist—is out to conquer the world through sheer musical charisma. Already hailed as one of the finest ensembles of their generation, and now in the middle of a three-year residency at the Chamber Music Society of Lincoln Center, in New York City, the DSQ will continue to win over North American audiences this fall with a tour that includes Chicago; St. Paul, Minnesota; Washington, D.C.; Vancouver; New York City; and La Jolla and Santa Barbara, California. Oct. 10–Nov. 18.
