I picked up one of her early albums, Tim's House several years ago off iTunes. It's very mellow and sparse without being too much of a drag.
Some of her other albums are nice, but they have more melancholy and are probably better in small doses. Still worth a listen when you're sliding into the end of fall and want to just catch your breath and enjoy the changes.
Sounds like: KT Tunstall. Eva Cassidy, or maybe Cara Dillon, only English.
