A recording of our final concert performance is now available for streaming (above) or follow this link here

This recording was made at the University of Minnesota on March 10th, 2016 as the final phase of this New Music USA project.

Thank you to all that supported us in this project! We were not only able to present this work in the original proposed form in the Twin Cities, but this piece also took us from Minneapolis, MN to Denton, TX to New York City to the World Saxophone Congress in Strasbourg, France. It has been a privilege to meet so many new people, and in the process of presenting this work, to hear so much new music from other musicians from around the world as well. Ben and I will continue to collaborate on this work in the future (the second movement was recently performed at Ball State University in March 2016) and are planning on releasing an album of this work with other contemporary saxophone music.

We also want to express our sincere gratitude and thanks to New Music USA for helping us make this project possible.

Minneapolis-based saxophonist Benjamin Cold is partnering with composer Sam Krahn to commission a new 35-minute work for solo saxophone and electronics entitled flux-mirror.

flux-mirror is a large-scale work written specifically for saxophonist Benjamin Cold. The focus of the piece is a gradual evolution of range, timbre, and the use of electronics over 35 minutes. A different saxophone is featured in each of the three movements: first alto, then baritone, and finally bass. Electronics become increasingly present, leading to an incorporation of live electronics with Max/MSP software in the third and final movement. In addition to this focus, flux-mirror explores symmetry and reflection as evolving, shifting states. Microtonality, micro and macro time structures, and spatial relationships between performer and electronics are also pursued. The first section, for baritone saxophone and tape, was finished in April 2014 and performed by Ben on April 11th, 2014. The remaining movements will be composed for future performances in March 2015, described below.

The completed 35-minute piece will be performed on two separate recitals: a concert on the University of Minnesota Twin Cities campus on March 23rd, 2015 and a second concert on March 30th, 2015 at Studio Z in St. Paul, MN. These recitals will feature works for solo saxophone and electronics by living composers. Both will be free, open to the public, and will provide opportunities for Sam and Ben to network with new audiences.

Prior to the March 2015 performances, Benjamin Cold will perform the first completed section of the piece in contemporary saxophone music recitals at Kansas State University on December 3rd, 2014 as well as at the University of North Texas on November 19th, 2014. During these concerts, Sam will be able to receive important and informative feedback about his current work, which will ultimately inform the finished composition.
