SōSI 2020 Online

*Applications for the Collaborative portion of SoSI 2020 Online are closed. Registration for the online course (no application) is open until July 6th!

Announcing SōSI 2020 Online, a new summer course from Sō Percussion! In place of our 12th annual Sō Percussion Summer Institute on the campus of Princeton University, and in light of the current situation we are all in with the Covid-19 national emergency, we are designing a new virtual SōSI with two main tracks. Although SōSI is normally limited to percussionists and composers, SōSI Online is available to musicians of any instrument or creative discipline in music.

Collaborative SōSI is an online festival where participants work towards common realizations of new work, reinterpreting older work that suits online collaboration, and sharing their own projects, with multiple opportunities to share with the public through So’s channels. The festival culminates in a “Day of Awesomeness” marathon stream of work from the festival on Sō Percussion’s social media.

“This is a moment to be creative and make work that is different from what we normally do.”

Percussion member Jason Treuting

SōSI alumni Daulton Mattingly and Kirstian de Leon sport their SōSI t-shirts for a new realization of Jason Treuting’s June, part of So Percussion’s program The June Project.

OPTION 1) Collaborative SōSI – an interactive festival of online collaboration with other participants and Sō Percussion. Open space is limited. Brief free application. Application open until May 29, 2020!

  • Tuition – $500

Details about the program:

Five areas of activity:

  • New Works (for remote collaboration) – New pieces written for SoSI 2020 Online, harnessing the unique challenges and opportunities of online collaboration. We will need creators and interpreters to bring these to life!
  • Past Works (in remote collaboration) – Some pieces in the experimental and percussion music traditions use conceptual frameworks which lend themselves to remote collaboration. This includes works based off of a stopwatch, ambient pieces, pieces with chance operations, etc.
  • Go placidly amid the noise – Jason Treuting’s signature pieces for flexible instrumentation can be built in layers and change from one realization to another. Participants will collaborate on fresh new versions of these pieces.
  • All Play: Large Works for flexible instrumentation. Each year at SoSI we feature one large work to involve as many participants as possible, such as Steve Reich’s “Drumming” or Terry Riley’s “In C.” We will do 1 or 2 of these projects.
  • Creative Salon: Anything goes! Free forum for participants to collaborate and feature things they are excited about. Could be a composition, a performance of existing repertoire via remote collaboration, or another personal creative project.

  • Held during the same 2 weeks of July that SōSI was scheduled for: July 12-26, 2020.
  • Creative laboratory to make and perform new works through online collaboration, with direct mentorship from Sō Percussion.

    Guests from Past Years

    The past years of the Summer Institute have included masterclasses, talks, and performances with a great number of amazing artsists including Caroline Shaw, Paul Lansky, Steve Mackey, Dan Trueman, Steve Reich, Steve Schick, Angélica Negrón, Dan Deacon, Martin Schmidt (of Matmos), Juri Seo, Barbara White, Lukas Ligeti, Grey McMurray, Cenk Ergun, NEXUS, Joan Tower, Tristan Perich, Suzanne Farrin, Mark Dancigers, Dennis Desantis, and Sarah Kirkland Snider.

    The Institute’s Mission

    The emergence of the percussion group as a standard ensemble has been one of the most exciting developments in contemporary western music. Sō Percussion was formed to expand this important voice in the 21st century, taking a cue from groups in North America and Europe, as well as the pioneering composers who inspired them.

    Since its inception in 1999, education has become an increasingly important part of Sō’s mission. Its members share a firm belief that inherent in an artist’s career is a responsibility to pass on practical advice and mentorship to young artists. The Sō Percussion Summer Institute seeks to fulfill this promise by providing a unique educational opportunity to percussionists and composers at one of the most critical stages of their development. The program offers a hands-on experience that brings the practical and theoretical together:

        • Commissioning/Creating new music
        • Fruitful collaboration with and among artists
        • The rehearsal and development process
        • Performance

Sō Percussion Summer Institute Opening Concert 2020

Welcome to SōSI! When we founded the So Percussion Summer Institute in 2009, we set out to create the chamber music summer festival we wish had existed when we were students. We launched a two-week program in Princeton, NJ where emerging percussionists and composers could gather and collaborate, benefitting from performing alongside seasoned pros and playing unique works by living composers—often for the first time. Over the last eleven gatherings of SōSI, we’ve done just that, providing hundreds of percussionists and dozens of composers with the opportunity to explore the new, hone their skills, and become part of a community of idealistic creators and interpreters.

This year’s SōSI looks a little different—we’re gathering online, which allows us to welcome artists from around the world—but we are so proud of what these students are creating with us. Enjoy!

When social distance became a necessity (and we faced an abruptly bare concert calendar), we decided to use the time and space to create a new version of a signature work,  Jason Treuting’s Amid the Noise. Written for flexible instrumentation, Amid the Noise lends itself well to  layering and technological artistry. The process of interpreting each movement (some with the quartet, and many more with musical colleagues) helped us understand what felt right for socially distanced creative work – and how we wanted to record and layer it all together. 

This learning process has shaped the structure of SōSI 2020 Online, and we are delighted to premiere the complete Amid the Noise 2020 for you as our opening concert. 

There is much to come over the coming weeks, and we can’t wait to share more work and creative collaboration with the brilliant students of SōSI, and with the greater public. 

Stay tuned, and be well!

-Eric, Josh, Adam, Jason, and Shelby

P.S. – After the show – Jason Treuting will host an Instagram Live to chat the genesis of Amid the Noise – join us on Sō Percussion’s channel –  @sopercussion! 

This is a free concert. Help us continue our work within SōSI by making a donation!  

100% of contributions made during this event will go directly to The Outreach Program

For the past six years, Sō Percussion has partnered during SōSI with The Outreach Program to pack meals for food-insecure families in Mercer County, NJ. COVID had other plans this year, but we’re still committed to The Outreach Program’s great work. When we host SoSI on Princeton’s beautiful campus, our annual food-packing event reminds students that many of Princeton’s neighbors in Mercer County struggle with food insecurity. The percentage of food-insecure residents in Mercer County has grown amidst COVID-19, rising from 8.9% in 2018 to an estimated 13.6% this year. Now more than ever we are honored to partner with The Outreach Program: any gifts to Sō Percussion during SōSI (July 12-26, 2020)  will go directly to The Outreach Program.

Each year, an amazing team of interns helps us keep this extremely complicated festival going!  Interns have usually been SōSI alumni who come and help us organize gear, produce concerts, and keep the ship running.

The bulk of our interns’ duties fall within logistics for a festival which hosts dozens of world premieres by 40-50 percussionists each summer. They receive free room and board during the festival, and frequently participate in performances themselves.
