The Benevento/Russo Duo continues to work its way into the Phish framework. Last night, at South Burlington, VTs Higher Ground, both Mike Gordon and Jon Fishman joined the paired performers, along with an additional series of special guests. First, the Slips Brad Barr joined the Duo onstage, adding guitar to much of the groups set (an old friend of Marco Benevento, Barr performs on Darts, the Duos first release). Next, Fishman emerged, marking the first time the former Phish drummer has performed with the Duo. During the Duo’s encore, Fish returned with Gordon for Mikes Song, with Jazz Mandolin Projects Jamie Masefield and Mad Dog also appearing on the song’s outro jam. For those keeping score at home, Page McConnell has also jammed with Benevento, Russo and Gordon when the trio played Higer Ground on December 30, 2004. In other Duo news, the 2005 Jammy winners have made a new track from its studio forthcoming album available on its homepage .
