Austin chamber-folk chanteuse writes a stunning collection of “lullabies and lightly dark fairy tales,” then crowdfunds $10,000 to record it with the internationally acclaimed Tosca String Quartet, which has worked with David Byrne, Bonnie Raitt and Arcade Fire, among others. Like so much in Austin, Ivey and the quartet’s February 13 CD release party for Whisper of the Moon will be a true one-of-a-kind experience.
