Saturday at the Opera (Online)

OperaVision, a consortium of opera houses, has collected and posted an amazing number of first-rate performances that are available for free viewing. They won’t be for much longer, so now is the time to see what the excitement is about if you’re new to opera – or if you’re an aficionado, enjoy rarities like Erich Korngold’s Violanta and new work like Stuart MacRae and Louise Welsh’s Anthropocene, (right).
