“There’s an old saying about rock and roll being nothing more than ‘three chords and the truth,'” Bob Mould said during a Reddit AMA yesterday. “I thought they said ‘three words.'” The former Sugar and Hüsker Dü frontman found a way to be even more economical with the title of “Ice Cold Ice,” from Hüsker Dü’s relatively polished 1987 double-album swan song Warehouse: Songs and Stories. As Rolling Stone points out, during the online chat Mould unveiled a clip of a jubilant Grohl joining on guitar and backing vocals for a performance of the song. The video, a sneak preview of the See a Little Light: A Celebration of the Music and Legacy of Bob Mould concert film (see: How to Make Bob Mould’s Tribute Concert Film a Reality) captures a precision-pummel alt-rock display that carries all the exuberance of kids opening up their toys on Christmas morning, not highly proficient pros performing a 25-year-old song. No surprise that’s also the defining mode of Mould’s latest solo work: intensity, joy, and the truth.
