A restless collective of medieval experimentalists, the Flatbush-based band Alkemie recently gained recognition beyond Brooklyn with their soundtrack for the video game Pentiment. Comprised of singer-performers playing over a dozen instruments (including vielles, harps, psaltery, gittern, recorders, douçaines, and percussion), the ensemble has a particular interest in the porous boundaries between the Medieval period and our time. Locally and nationally, they have been presented by the Amherst Early Music Festival, Arizona Early Music Society, Cambridge Society for Early Music, the Berkeley Early Music Festival, Five Boroughs Music Festival, Johns Hopkins Program in Arts, Humanities & Health, and Music Before 1800.
