Any project featuring one of the world’s most famous opera singers reinterpreting the songs of Arcade Fire, Band of Horses, and the Mars Volta must rate pretty high on any WTF scale, right? But that’s just what Renée Fleming is doing on Dark Hope, which could be pretty compelling whether you’re interested in the vocal pyrotechnics or the possibility of a stylistic trainwreck. If the song samples in the promo video are any indication, it sounds like today’s art rock hits might make for tomorrow’s easy listening, as Fleming puts the diva in emo on numbers by Death Cab for Cutie and Muse. And maybe we don’t need another version of “Hallelujah” even if it’s performed by the best singer alive, something that Fleming herself seems to appreciate in the video. But as the promo attests, one thing you have to give Fleming credit for is taking this somewhat absurd idea seriously. Dark Hope will be released on June 8, while Fleming’s cover of Muse’s “Endlessly” is already available at iTunes.
