Kate Walsh has stepped back into a world she's come to know so well.The "Private Practice," star headlines a new indie drama called "Angels Crest," in which she plays a lesbian artist in a small-town tale alongside Jeremy Piven and Mira Sorvino. The perhaps oxymoronic gruff artist was a role she very much enjoyed."I loved the character, and the relationship between her and her partner was really interesting to me," Walsh told The Advocate.
