Chanticleer charmed the crowd Tuesday at the Ramsi P. Tick Memorial Concert Series. The 12-voice men’s singing group from San Francisco presented an unorthodox program, from plainchant and medieval carols through Ligeti and music by a West Coast deejay, Mason Bates. The singers won everyone over.

“That was wonderful.” That was what you heard, over and over, as you were walking out.

The performance was a hot ticket, and the Tick organizers took the occasion to announce the concert series’ next season. It begins Oct. 22 with a solo recital by pianist Andre Watts and also includes David Finckel of the Emerson String Quartet and his wife, pianist Wu Han, as well as a recital by Athenianborn violinist Leonidas Kavakos. Chanticleer will be back, too. So if you missed this performance, all is not lost.

Chanticleer has such virtuosity that their voices tend to blend seamlessly into one big, pure sound. It’s fun to play games and try to figure out, for instance, which of these men is singing the high, fluttery soprano. It’s not always easy.

The singers’ first set focused on, but was not limited to, early church music, including Orlando Gibbons and Palestrina. It was all enchanting, but the battle set that followed was even better. The “Agincourt Carol,” which chronicled Henry V’s triumph over the French, showed off Chanticleer’s superb diction. You actually could understand the Middle English, even without the text.

The singers engage you on many levels, physically as well as musically and emotionally. Formally clad in white tie and tails, they open their books all in the same instant and bow in perfect sync.

Renaissance composer Gillaume Dufay’s “Lament of the Holy Mother Church of Constantinople” was a sleeper hit. It was so light and beautiful, as if it came out of the air.

Even that paled next to Clement Janequin’s “The Battle of Marignano,” a mesmerizing medieval saga involving all kinds of vocal effects — whirs, rolling “r’s” and various nasal sounds that probably have not been heard much since 1600.

The second half, mostly modern, included three songs by Bates, the deejay. They were interesting, if opaque.

Three songs in Spanish culminated in the hilarious “The Peanut Vendor,” a hit in the 1930s and still a lot of fun. “El Grito,” by Carmen Cavallaro, spotlighted the singers’ feminine sound. It soared into rapturous waves.

Chanticleer is one uninhibited group. As an encore, one of them stepped forward and sang soprano solo in “Summertime,” with the rest of the group backing him up. What a feat!
