Guests at the upcoming concert performed by the Avanti Chamber Singers are in for a surprise.

Voices Raised, led by Rachel Rensink-Hoff on Saturday, Feb. 23, is a chance for Brock University’s choir-in-residence to celebrate the raw power of the human voice.

The group will be performing an a cappella concert, with pieces ranging from early classical works to contemporary repertoire. The show promises to be the most diverse concert to date, with everything from open-throated chant singing to spoken word poetry.

Members of the Avanti Chamber Singers have been working hard since their performance last November to build confidence with pitches and tuning, since there are no accompanying instruments this time around.

“I am proud of what Avanti has accomplished in the short period of time since our last concert,” said Rensink-Hoff. “We can’t wait to share this program with our audience next week.”

The group will also be performing a bit of beat-boxing and a deeply moving text by Indigenous poet Rita Joe titled I Lost My Talk. The singers will also be premiering two new compositions — one by Niagara-based composer James Moffett and the other by Laura Hawley.

The Avanti Chamber Singers will also be inviting the audience to join in a singalong during the concert.

Seating at St. Thomas’ Anglican Church is limited and guests are encouraged to purchase their tickets as soon as possible.

Voices Raised takes place Saturday, Feb. 23 at 7:30 p.m. Advanced tickets are available through the Avanti Chamber Singers website, at Thorold Music and Booksmart, or from choir members for $20 for adults and seniors. Tickets at the door are $25 for adults and $20 for seniors. A $5 ticket is available for students and eyeGo program members.

Rensink-Hoff is also the conductor for the Brock University Choirs, which includes both the chamber choir and the new women’s choir. Their next performance is Saturday, March 30.
