This is one of the area's most accomplished vocal ensembles. Chicago A Cappella is performing on Sunday, April 10th at Pilgrim Congregational Church, 460 Lake St. in Oak Park at 4pm. Their repertoire goes from Gregorian chants to the Beatles, as the attached video clip shows, and beyond. They are in their 18th season and just get better and better. You are in for a treat when you see and hear this group. Tickets at 773-755-1628 or 1-800-SING-WOW or their site at www.chicagoacappella.org .
