IRON RIVER — The 21st annual Summer Concert Series at Grace Covenant Church in Iron River continues at 6 p.m. Saturday when The Vocality Quartet, an a cappella group from White Bear Lake, Minn., will make its Iron County debut.

“The Summer Concert Series is one of our favorite traditions,” said Erika Lindwall, worship committee chairwoman at Grace Covenant Church. “We’re delighted to continue the legacy with this season’s artists and hope that many will come to share in worship and praise, and enjoy the tremendous talent coming to Iron River.”
