Björk gave the world premiere of her Biophilia live show last night, launching the Manchester International Festival. The New York Times says: "The new songs juxtapose hovering textures of choir and organ with sparse pointillism and sudden eruptions of breakbeat drumming, all set against Björk’s idiosyncratic melodies." The Guardian gives the concert four stars: "Bjork's voice still sounded gloriously childlike and otherworldly, a voice from what at times literally felt like a parallel dimension." The Times of London gives four stars as well: "For all the gadgetry and theatricality of this show, the elemental voice at its core was still the most remarkable instrument." The Manchester Evening News calls it "extraordinary."

The Cincinnati Opera performs John Adams's opera A Flowering Tree tonight and Saturday, reuniting the world-premiere cast featured on the Nonesuch recording of the opera: soprano Jessica Rivera, tenor Russell Thomas, and bass-baritone Eric Owens. The Cincinnati Enquirer says "Adams takes a striking new path" with A Flowering Tree, "combining an exotic story of magical transformation and love with ravishing music ... lyrical, lush and dreamlike." Watch a preview of the production and go backstage in videos here.

Laurie Anderson gives a free performance with bassist/producer Bill Laswell at Castle Clinton in NYC's Battery Park tonight as part of the River to River Festival. "Many musicians might bill a performance as a chance to 'build on new ideas and forms,'" says the Wall Street Journal, "but few could make as good on the prospect as Laurie Anderson and Bill Laswell." The New York Times describes the performers as "unusually fearless; expect something high-concept and possibly explosive."

The Black Keys kicked off their trans-Canadian summer tour with sold-out shows in Vancouver and Calgary.

Auerbach and Carney just nailed it." Vancouver's Straight calls it "a blistering, glorious motherf*cker of a set."
