With gorgeous cover art, a hefty CD booklet and an overwhelming tracklist, Sunny Day suggests Smithsonian Folkways is hoping for a Dan Zanes event with Elizabeth Mitchell. (Zanes, a friend, even guests on the album.) They shouldn't push it, though; her brilliance is more intimate and sweet than Zanes'. The biggest pleasure on Mitchell albums is her smiling voice and preference for quiet over raucous. The best moments come in songs like "Elephants All Over the World" and "Tsuki," which simply invite us to share in her sense of wonder.
