Make room on your Sunday evening for an hour of decapitation, cannibalism, and supernatural vengeance by millstone.

No, it’s not “60 Minutes.” The Cleveland Institute of Music Opera Theater is presenting Philip Glass and Robert Moran’s collaborative opera, “The Juniper Tree,” tonight at 7:30 EST.

This grimmest of Grimm fairy tales has a little something for everyone. It was Maurice Sendak, who certainly knew a thing or two about wild things, that first suggested the subject. In perhaps the opera’s greatest irony, it is Moran who manages to find beauty, and even tenderness, at the heart of this black fable.

“The Juniper Tree” was first performed at the American Repertory Theater, in Cambridge, MA, in 1985. Among the cast were Jayne West and the late Sanford Sylvan. Glass retained ownership of the opera and held back on releasing the recording until 2009. In the meantime, Moran encouraged fans to distribute their bootleg copies.

CIM has been streaming this weekend’s performances, from a three-day run of an all-new production. I was unable to access last night’s performance, but I’ve got my fingers crossed for better luck tonight.

The transmission will originate from a fixed camera situated at the rear of the hall, so the action may be a little distant, and some peripheral details in the side balconies lost, but here’s hoping story and music manage to retain their impact.

Here’s a link to tonight’s livestream. Vimeo may require you to register, so be sure to do so in advance.
