Mike Watt, 'Ball-Hog or Tugboat?' (1995)
"One of the most blow-away players," former Minutemen bassist Mike Watt said of Grohl in 2011. "I know he doesn't like to play drums much nowadays, but man he was something else." Sixteen years earlier, Grohl had played on Watts' solo debut album, Ball-Hog or Tugboat?, which also included Eddie Vedder, Flea, Thurston Moore and Grohl's ex-bandmate Krist Novoselic. The album's sessions were the first time Grohl recorded in a studio after Kurt Cobain's death.
