When the gigantic dome of the largest of the several observatories atop Mount Wilson slowly rotates and cracks open like a reptilian eye to reveal the sun, sky and mountains outside, it becomes the most spectacular setting in Southern California to witness a concert. The cycling sounds generated inside the metallic dome housing the historic 100-inch Hooker telescope take on an unusual, echoing resonance, which should make the monthly Sunday Concerts in the Dome series’ presentation of “Songs of the Spheres” feel especially haunting.
Sopranos Hila Plitmann and Sangeeta Kaur raise the (spherical) roof with the world premieres of six vocal compositions by Danaë Vlasse, Bruce Babcock, Anthony Constantino, Todd Mason and Mark McEncroe.
