We have been inspired by many wonderful collaborators.  Their contributions help us create unique music that neither of us would have come up with on our own.

Caroline Shaw


One of our favorite recent collaborations is with the Pulitzer-prize winning composer Caroline Shaw, which also involves the legendary soprano Dawn Upshaw and pianist Gil Kalish.

We first came together with Upshaw and Kalish to perform George Crumb’s massive song cycle Winds of Destiny. Out of this collaboration, we decided to commission a new work for the six of us. Upshaw was the featured artist for the Music Accord project (an association of music presenters who collaborate every year on commissioning new works). When she approached us about this new piece, the first composer who came to mind was Caroline Shaw.

The work that resulted, Narrow Sea, is a heartbreaking and intimate exploration of the themes of the wanderer and the refugee. As with Crumb, the songs are sourced from American folk traditions, forming an entire program that explores American songs and hymns with percussion.

We recorded Narrow Sea, along with Shaw’s percussion quartet Taxidermy, this past summer. During the session, we stayed an extra day with Caroline to make some new music together. The experience was so invigorating that we went back to Guilford Sound in Vermont in October to create what turns out to be an entire new album of songs! We incorporated original music from both So and Caroline, using text from James Joyce, traditional folk songs, and our own work.

We premiered Narrow Sea at Penn State in October of 2017, with further concerts at San Francisco Performances, UCLA, The University of Richmond, and the Kennedy Center.

Shara Nova

Carnegie Hall, as part of their “125” commissioning project, sponsored a new work for Sō Percussion and Shara Nova called Timeline. Timeline represents the first occasion on which Sō Percussion and Shara have worked together. We’ve admired her work for many years, both as My Brightest Diamond and on works such as David Lang’s Death Speaks. Shara’s haunting voice and penetrating verses explore the subject of time, and as such provide Timeline as a kind of companion piece to Steven Mackey’s It Is Time.

Working with Shara was one of those moments of instant chemistry for us: she is a consummate, almost frighteningly gifted musician. She handles our typically quirky rhythmic layers with grace, but then adds a lyricism and emotional depth that makes our mutual exploration come to life.


Buke and Gase

2014_03_26_EMF_77Our collaboration with Buke and Gase began at the Ecstatic Music Festival in New York in 2014. Since they perform on custom-designed instruments – “Buke” is baritone ukulele, “Gase” is a hybrid guitar/bass – it wasn’t difficult to find common ground. Buke and Gase also love to experiment with complex overlapping rhythmic loops, which only helped!

We’ve just recorded a new album together, and we’ve had performances in New York, at the Big Ears Festival in Tennessee, and the Walker Art Museum.

Here’s our set from the premiere on New Sounds Live at the Ecstatic Music Festival: March 26th, 2014 at Merkin Concert Hall. Our combined performance starts at about 1:13 into the show.



The very first time we sought collaborators outside of the classical and new music world, we found Matmos. The now legendary duo specializes in making music with strange and ordinary objects: their most recent effort is an album made entirely out of washing machine sounds. They opened entirely new horizons to us…after working with Matmos, we began incorporating more electronics and found sounds into our own music.

In 2010, we released Treasure State on Cantaloupe Music. One of the most popular pieces from that record is “Needles,” our own take on John Cage’s idea of the amplified cactus.
