You are invited to a celebration of the completion of the Alexander McGaffin Carillon lighting project. At 9pm on Wednesday 10 August the Church of the Covenant will switch on the lights for the first time while we peal the bells. A half-hour carillon concert by George Leggiero and Keiran Cantilina will begin with a performance of Hail Mary by Cory Arcangel, the quirky piece commissioned by FRONT International. Each day the performer improvises on a new iteration distributed via Twitter bot. There will be refreshments. We hope to see you there!
