Latvian Ēriks Ešenvalds is one of the most sought-after composers working today, with a busy commission schedule and performances of his music heard on every continent. Through a connection with Music Professor Mark Vuorinen, Ešenvalds offered a seminar and singers’ workshop in partnership with Grebel’s three choirs and the Grand Philharmonic Choir in February. Enchanting the large crowd with his insightful comments and entertaining musical direction, Ešenvalds brought a sparkle of light to an otherwise dark evening.
