Frey’s [Streichquartett], while likewise partaking of a Feldmanesque aura, realizes something more static and compact. Even on repeated hearings the Swiss composer’s work ends abruptly. [(Unbetitelt) VI] contains long solo passages of uneven scales, reminding one of skyward ladders. Its few chordal moments startle. The two Zwei allerletzte Sächelchen are sub-minute phrases. Frey’s hushed [Streichquartett no 2] will take your breath away, notwithstanding a resemblance to one’s final earthly moments. EWR captures a delicate sonority, sounding like quiet humming, muted bowing and hushed sul ponticello tremolando. This otherworldly quartet conjures the a cappella passages of Verdi’s Requiem.
