This past Saturday, January 6th at Radio City Music Hall in New York, music fans from all over came together for an evening of charitable giving and fantastic music at A Concert For Island Relief. The show featured performances from Hurray For The Riff RaffAaron NevilleTrey Anastasio Band and, finally, a Dave Matthews solo acoustic set to close the evening.

However, while Dave’s set was predominantly a solo affair (aside from some added brass on “Mercy”, “Satellite”, and “Save Me”), the highlight of his set came at its end, when he returned to the stage and invited Anastasio to join him for a duet on the first of four encore songs.

Trey took the stage with an acoustic guitar, and together the two ran through a beautiful version of Phish‘s “Waste”, written by Anastasio and Tom Marshall more than twenty years ago. Following the performance, which saw Trey and Dave trade verses before harmonizing on the chorus and bridge sections, Dave giddily leaned in to the microphone.”That’s Trey,” he remarked, pointing to Anastasio. “That’s my favorite song.”

That assertion from Matthews has plenty of historical background. Dave Matthews Band covered the song 15 times on their 2001 tour, and two more times in 2002. Then, during Phish’s hiatus, Trey joined Dave on Dave & Friends tour, during which the pair would include an acoustic duo portion of their sets, covering songs from both Phish and Dave’s catalogues–often including “Waste”.
