Chorus pro Musica's former director Jeffrey Rink returned to conduct the group on Sunday; its 60th-anniversary season closed with concert opera, an annual tradition Rink started in the 1990s. Putting the grandeur of "Turandot" into Jordan Hall is somewhat like putting a rock band into a phone booth, but Puccini's swan song is an opera to be happily overwhelmed by, and the group delivered in formidable fashion.
"Turandot" also ranks as a choral showpiece; especially in its first act, with the titular princess at a distance but her murderous regard for unworthy suitors front-and-center, the crowd carries huge stretches of the drama. The chorus (prepared for this concert by Steven Gearhart) dove in with brio, rhythmically grounded, textually clear, ranging in color from spectral hush to quintessential grand-opera peroration. (A contingent of children from the Boston City Singers lent tonal innocence from the balcony.)
