Sandbox Percussion and UW School of Music students and faculty come to ECM to give a performance of Simeon Ten Holt’s evening-length minimalist work, Canto Ostinato. Originally a keyboard piece by the Dutch composer, Canto Ostinato is made up of overlapping layers and repeated patterns, and has amassed a cult following. Conceived and developed by Andrew Cyr, Erik Hall, and Jonny Allen, this version of Canto Ostinato features a 17-piece ensemble arrangement led and commissioned by Metropolis Ensemble’s Founder and Director Andrew Cyr. As Canto Ostinato is commonly performed with either two or four pianos, this ambitious arrangement highlights the musical freedom of Holt’s most popular work, which can be performed by different instruments and a varying number of performers.
