Paying tribute to one of the Big Apple's artistic landmarks -- the Amato Opera House -- this hourlong PBS documentary also salutes its spirited founders: Tony Amato and his wife, Sally. Staging full-scale productions from a tiny brownstone, the Amato has served as a launching pad for rising opera stars since 1948. Performance excerpts and interviews with illustrious Amato alumni help chronicle the charming venue's 50-year history.
