From the baroque balcony overhanging The Danforth Music Hall's cement orchestra, the stage was emanating a midnight-blue membrane—think a gothic emu egg—with fuchsia highlights speckling the drum set and many candelabras. If that palette sounds familiar, double-check the packaging of the latest album by Weyes Blood (Natalie Mering), And in the Darkness, Hearts Aglow (AitD,HA). This stage is where the cover's heroine lives during the Holy Flux tour, a high-romantic dreamscape ascending the east coast to settle in Toronto for two evenings last week.
