Hüsker Dü was a rock band formed in Minneapolis-St. Paul, Minnesota in 1979. The band's continual members were Bob Mould, Greg Norton, and Grant Hart.

Mould and Hart split the songwriting/singing duties, with each singing only the songs he had written, though they occasionally harmonized vocally. Mould's lyrics were known for being more soul-searching and intense than the often whimsical and cryptic ones of Hart. Hüsker Dü first gained notice as a hardcore punk band with thrashing tempos and screamed vocals, but also with a melodic, soulful edge that became more pronounced in the band's mid-career as they drifted away from their early sound, becoming one of the most influential bands in American alternative rock in the process.

Hüsker Dü never achieved mainstream success, but attained an impact far larger than their modest sales figures would indicate.[1] They are notable as one of the first 1980s American underground rock bands to sign with a major record label, a move which blazed the trail for the breakthrough of alternative rock a few years later.
