When we met the Portland pop duo in New York last autumn, we spent an afternoon with them at the Moscot eyewear shop on the Lower East side. The former members of Andy Cabic’s backing band in Vetiver have been collaborating on songwriting for the last several years. And though their debut album, Moon Tides, is full of beautifully layered synths, ethereal vocals, electronic percussion and reverb-laden guitar, Sarah Versprille and Daniel Hindman shared with us sparse yet heart-rending acoustic versions of a couple of their most beautiful songs.
