Petr Kotík’s monumental, six-hour vocal-instrumental composition Many Many Women (1975–78,) a musical rendering of a novel/short story by Gertrude Stein, who has already provided inspiration for several pieces by the composer, will be performed by members of S.E.M. Ensemble. This unique staged performance of Kotík’s magnum opus by singers from New York and Graz marks the composer’s 80th birthday.
