Certain scores possess a kind of witchcraft that transforms an experience from “listening to” into “listening inside,” and our May appearance at the Logan Center Penthouse is just that, top to bottom. From the seductive melodies of Mendelssohn’s Quartet No. 1 in E-flat Major to the bracing exchanges of Bartók’s String Quartet No. 5, these works lure you inside their singular, charismatic worlds, and Arvo Pärt’s Fratres is an aural narcotic, the effects of which can last for hours.
