Also on the program are Britten’s “Serenade for Tenor, Horn and Strings,” a song cycle set to poems on the subject of night, with leading tenor Thomas Cooley and LACO principal horn Michael Thornton, and Haydn’s Symphony No. 104, “London,” a continuation of LACO’s multi-year exploration of the composer’s 12 London Symphonies.

LACO commissioned Reid as part of its successful commissioning program that engages LACO audiences in developing new works. It gives members the opportunity to observe first-hand the development of a new work from the composer’s earliest ideas to the finished composition. Reid’s work is largely collaborative and takes the form of opera, chamber music, electronic pop songs, immersive interactive media, and scores for film and theater.

Boyd, acclaimed for his vibrant conducting style, was a founding member and principal oboe of the Chamber Orchestra of Europe for 21 years before turning to conducting in 2002. He served as artistic partner of the Saint Paul Chamber Orchestra and made his LACO conducting debut in 2014.

The performance on Feb. 24 begins at 8 p.m. at the Alex Theatre, 216 N. Brand Blvd., in Glendale. On Feb. 25, the show begins at 7 p.m. and will be held in UCLA’s Royce Hall, 10745 Dickson Court.

Tickets start at $27. Discounted tickets are also available by phone for seniors 65 years of age and older, and groups with 12 or more. College students with valid student ID may purchase discounted tickets based on availability. For information and tickets, visit laco.org.
