Today's Sound Perimeter includes two journeys of motion and momentum: Gity Razaz’s 'The Strange Highway', racing forward with eight cellos like headlights through shifting landscapes; then a cello quartet in Carlos Gardel’s “Por una cabeza” leaning into tango’s sway, where a heartbeat rhythm meets a bittersweet tune. Together, they reveal the cello’s range, choral and intimate, resonant and lyrical, and how music can carry us through desire, risk and release. Featuring performances by Gity Razaz , Erin Murphy Snedecor and the Galvin Cello Quartet .
