Johnny Walker of the Soledad Brothers played slide guitar on two songs: "Suzy Lee" and "I Fought Piranhas". Walker is credited with having taught Jack White how to play slide, a technique featured heavily on the White Stripes' first two albums. Walker explains, "[Jack] had a four track in his living room and invited me to come by and do some recording. In return, I showed him how to play slide."
"Jack White's voice is a singular, evocative combination of punk, metal, blues, and backwoods while his guitar work is grand and banging with just enough lyrical touches of slide and subtle solo work... Meg White balances out the fretwork and the fretting with methodical, spare, and booming cymbal, bass drum, and snare... All D.I.Y. punk-country-blues-metal singer/songwriting duos should sound this good."
