We often imagine new pieces of music arriving like pristine dispatches from Olympus - unique, inviolable, and born whole from the depths of the composer's imagination. Not so for Osvaldo Golijov. The Boston-based Argentine composer works more like an 18th-century man of the theater: writing, revising, and recycling to suit the occasion, and often soliciting input from the performers in the process.
This week's program at the Boston Symphony Orchestra, led by Miguel Harth-Bedoya, is a perfect example. The first half is all-Golijov, including a work called "Azul," which he wrote for Yo-Yo Ma and the BSO. It was premiered at Tanglewood in 2006, and was conceived with the open air and deep sky of the Berkshires in mind. This year, Golijov overhauled the work for its "indoor" premiere as part of the Mostly Mozart Festival at Lincoln Center, working closely with another soloist, Alisa Weilerstein. Thursday night in Symphony Hall, Ma returned to the piece, taking on its newest version. But what music should go along with "Azul"?
