The concert was opened by Common Rotation, a quirky folky Americana trio from East Meadow, N.Y. The longstanding trio deserves attention for its lovely harmonies and instrumental prowess - Jordan Katz played banjo and trumpet (an unusual combo, but played at separate times of course); Adam Busch on saxophone, harmonica and glockenspiel and Eric Kufs on guitar. The trio played seven songs, more than most openers, including one that featured the concerts first notes by Ray and Saliers, who joined in for harmonies.
Ever the collaborators, Indigo Girls brought Common Rotation on stage for its set; the trio joined the girls for harmonies on "Reunion."
Common Rotation also sang with the Indigo Girls in their closing songs, "Salty South" and "Closer to Fine." The song the Indigo Girls sang with Common Rotation was "Chain of Command."
