Class of 2021 to perform 12-hour benefit concert Class of 2021 12-hour marathon and fundraiser (Courtesy of Grace Stringfellow) On April 30, the University of Colorado Boulder’s Class of 2021 will perform a 12-hour marathon concert to raise money for local musicians. The concert will feature more than 45 musicians from the College of Music’s graduating class, performing live from The Spark, a performing arts center in Boulder. The concert will be livestreamed on YouTube from 9 a.m. to 9 p.m. on Friday. All donations will go toward the Boulder County Arts Alliance’s Musicians Relief Fund. Last December, two seniors, oboist Grace Stringfellow and flutist Claire Gunsbury, decided to organize a Class of 2021 benefit concert to raise money for local musicians. They wanted to raise awareness about musicians’ financial struggles during COVID-19, while also connecting with local audiences beyond the College of Music.
