The Peabody Square Choral Artists will perform their second-ever concert this Saturday at 7 p.m. at All Saints Church in Ashmont. The group will perform a piece by Czech baroque composer Jan Dismas Zelenka aptly entitled “Missa Omnium Sanctorum,” from the Latin for “All Saints Mass.”

Conductor Michael Raleigh said the work is “perfectly appropriate for the space,” and that he expects listeners to be delighted by Zelenka’s idiosyncratic style of composition.

“His music is very quirky, very fun,” explained Raleigh. “He loves to set something up expectation-wise, and then he just twists it a little bit and kind of throws you off guard. The music itself is very virtuosic...it’s extremely fun to listen to, very playful and energetic.”

The roughly hour-long concert will be performed by a professional chamber ensemble of woodwinds, strings, and organ, and a vocal octet of professional singers.

Raleigh noted that each of the eight singers will perform a solo. The concert will again feature All Saints’ resident organist Andrew Sheranian.

Tickets, at $25, can be purchased online at eventbrite.com or at the door. There is a reduced admission price of $15 for students and seniors, and free admission for children under the age of 12.
