The Rush of the Brook Stills the Mind is an electro-acoustic percussion solo composed for me by Elainie Lillios. Elainie and I had been discussing a collaboration since 2011, and we began working on The Rush in earnest in early 2013. In May, with Elainie’s new score in hand, from a studio in Fairbanks Alaska, I recorded a large sampling of percussion sounds from which she designed and built the interactive electronic part to the work. I performed the world premiere at the 2013 nief-norf Research Summit in June, and a subsequent performance at Sick Puppy (SiCPP) in Boston later that month. The composition is inspired by a poem by Wally Swiss of the same title. The program notes written by Elainie and the full text of the poem follow.
