Hagen Quartet, formed 43 years ago in Salzburg, gave its final New York concert on Feb 19 before disbanding in 2026. In Haydn’s Op. 54, Lucas’s soaring violin ignited a flame, melodies shifting like new landscapes, hidden passages glowing like distant stars. Schumann’s No. 3 followed, restless with sighing motifs, urgent rhythms, and a cello’s lovesick song. In the Adagio, voices intertwined until Schmidt’s dotted ostinato pulsed into the finale—Schumann’s truth revealed at last.
