Last night, Joe Bonamassa and Gov’t Mule kicked off a joint tour at Vienna, VA’s Filene Center at Wolf Trap National Park for the Performing Arts. Each act offered a full set and, as many hoped, they also opened up their stages to some cross-pollination. Gov’t Mule played first and invited out Bonamassa for a memorable take on “Statesboro Blues,” the famed Blind Willie McTell tune that The Allman Brothers Band made their own decades ago, during their performance. Then, during Bonamassa’s portion of the show, Gov’t Mule singer/guitarist Warren Haynes returned the favor, emerging for a cover Billy Cobham’s “Stratus.”

Haynes and Bonamassa are longtime friends and have collaborated in a variety of settings over the years. The blues guitarist even recorded Haynes’ “If Heartaches Were Nickels,” which was first released by Kenny Neal in 1994, on his 2000 debut LP, A New Day Yesterday.

Gov’t Mule and Bonamassa will appear at Bangor, ME’s Maine Savings Amphitheater tomorrow.
