Concert Harmonic Chant Friday April 13th. AS220, Downtown Providence. 9pm – midnight. $8-10 sliding scale. A full concert at one of Rhode Island’s premier arts venues (AS220, 115 Empire St) with supporting performances by Hindustani Classical tabla player, Ajit Acharya, and the Assembly of Light Women’s Choir. New England-based tabla player Ajit Acharya began his training under the tutelage of Sri Sheshagiri Rao of Bangalore, India. He also studied extensively with Dr. Rajan Sachdeva, one of the most respected and prolific Indian music teachers in the midwest. His tabla apprenticeship continues under the guidance of Pandit Samar Saha of the Benares gharana (or style) of tabla. Ajit has accompanied instrumentalists, vocalists and dancers. He has also given workshops and performed extensively with fusion, jazz and experimental musicians. The Assembly of Light women's choir is a ramshackle collection of about twenty women from Providence, RI. They've been stealing hours to sing together since late 2008, when composer and singer Chrissy Wolpert invited a few women to her apartment to sing some songs she'd been working on. It went well. They kept coming back. As a frequently changing "cast" of women from various backgrounds and degrees of vocal experience and training, the group takes shape on its own terms, forms itself without pretense, and brings about brightness through dark music.
