Seattle Symphony didn’t have to look far to find a substitute for guest conductor Rafael Frühbeck de Burgos, who was to conduct “Carmina Burana” — his specialty — but fell ill during a performance with the National Symphony this month. SSO tapped its own Stilian Kirov (shown here), the orchestra’s enthusiastic associate conductor, to helm Orff’s massive work, which will feature not only the musicians but the Northwest Boychoir, Seattle Symphony Chorale and soprano Caitlyn Lynch, tenor Daniel Shirley and baritone Corey McKern. Covering is a big part of an associate conductor’s job, and Kirov has done so for SSO music director Ludovic Morlot (getting the call the night before a concert, no less) and for the Boston and Chicago symphonies. Catch ‘Carmina” 7:30 p.m. Thursday, April 3, 8 p.m. Saturday, April 5 and 2 p.m. Sunday, April 6 (206-215-4747 or seattlesymphony.org).
