Congratulations to Caroline Shaw and Sō Percussion—Eric Cha-Beach, Josh Quillen, Adam Sliwinski, and Jason Treuting—who won the GRAMMY Award for Best Chamber Music / Small Ensemble Performance, for their album Rectangles and Circumstance, at the 67th GRAMMY Awards Premiere Ceremony held in Los Angeles today.

Rectangles and Circumstance comprises ten songs co-written and performed by the artists. Shaw and Cha-Beach and Sliwinski “sourced a group of nineteenth-century poems that shaped its expressive mode [and] ended up using verses by Christina Rosetti, Emily Brontë, Emily Dickinson, Gertrude Stein, and William Blake,” says Sliwinski. “The lyrics on this album by members of the band contain wordplay that explores the same profound feelings explored by Blake and Dickinson.” Shaw and Sō co-produced the album with Grammy-winning engineer Jonathan Low (The National, Taylor Swift). Ringdown—Caroline Shaw’s duo with Danni Lee Parpan—is featured on the track “Slow Motion.” You can hear the album here.

Caroline Shaw’s two Nonesuch albums with Attacca Quartet, Evergreen and Orange, previously won the Grammy for this category.
