Sisters Sierra and Bianca Casady’s second album continues where their debut La Maison de mon Reve left off. Haunting sounds of harps and acoustic guitars broken up by glitchy beats, the noise of Speak’n’Spell and one of those tin cans that moos like a cow when you up-end it. Bianca’s voice, reminiscent of Billie Holiday in its cracked blues vernacular, weaves in and out of Sierra's softer, more operatic tones. But if you’re not scared by its oddity, it’s the sort of music you'll fall in love with.

The pair began making music when Bianca turned up unannounced on the doorstep of the Sierra's apartment in Paris, where she was finishing her classical music studies. They hadn't seen each other for over a year. “I was living in New York and decided to just go somewhere,” explains Bianca. “I didn't really know what I was doing or where I was going, I was just running away. I stopped in Paris and didn't intend on staying, but something magical occurred and we were enjoying ourselves so much that I didn't leave. It's something we can barely recall, the notion to record. But there was a sort of impulse to document what was happening, so I bought a really simple recording device and the whole first record spilled out of us. It was just a whim. A strange whim.”

Noah's Ark was recorded away from the intimate confines of the Parisian apartment, on the road. “That strange glamour we possessed due to the isolation in Paris actually reappeared in different forms,” recalls Sierra. “We were able to render that really intimate space that we share, even as we travelled. That meant pulling over on the side of the road and just recording in a field, or taking a moment in a barn in the South of France, or a studio in Brooklyn.”

The new album is cut from the same strange cloth as the first one but it's more diverse. As well as the extended recording environment, the album features collaborations with like-minded souls, such as Devendra Banhart and Antony (without The Johnsons), who lends his astounding falsetto to Beautiful Boyz: “The people that we chose really fit the part and were really close to us during the process,” says Bianca. “It sort of reflects where we're at during this time, as opposed to the first record which really reflects being removed from everything.”
