Jenny Lewis through sincere, simple showmanship, gracefully proved the wealth of her last few year’s strive to become a better artist. Singing “Pretty bird / pretty bird” with a subtle longing, commanded the Outdoor Theatre. Later, her cautionary refrain, “He’s the next messiah” was simultaneously comforting and rocking, in a vein most notably found in The Eagles material. Lewis has found her voice, and it’s wonderful to see her come into her own.
