Alchymy Viols offers performances from some of the country’s finest players on the viola da gamba: Wendy Gillespie, Joanna Blendulf, Erica Rubis, and Robert Bolyard. Those who have attended performances know that Alchymy concerts include more than viols alone, a programming practice that derives from Alchymy’s name.  According to Alchymy’s founder and consort bass player Philip Spray, Alchymy Viols’ mission is to mix viols with other artistic elements to create a music event richer than the sum of its collaborative parts: with Indianapolis Early Music Festival bands, Bloomington Early Music, Dana Marsh and the HPI, Haymarket Opera dancers and director Sarah Edgar. Alchymy has drawn on less-likely collaborations as well: with Scottish folk fiddler Tim MacDonald to offer a chamber version of Scotland’s first opera, and with Paul Krasnovsky and Indianapolis’s contemporary music choir Mon Choeur. Alchymy Viols will soon release their first recording of America’s early music on Navona records: Deep River, American Spirituals, mixing viols and Stephanie Hall’s pedal harp with countertenor Michael Walker.
