Dirty Work is not the best Rolling Stones record of the 1980s. The Stones began the 1980s with Emotional Rescue (1980), Tatto You (1981), Still Life (1982), and Undercover (1983).
Dirty Work is not as good as any of them: it's not as dirty as Undercover, it's not as inspired as Tattoo You, it's not as original as Emotional Rescue. But Dirty Work is certainly one of the most underrated Stones record.
One Hit is a great rock. Harlem Shuffle is a nice cover. Dirty Work is a very energetic piece. And then you have some of the best Keith.
Dirty Work is the first album in which Keith sings two songs. Too Rude is a beatiful slow reggae which became a staple in his tour with the Expensive Winos. And then there is Sleep Tonight, which is a great slow song, in the best Rolling Stone tradition. It is probably Keith's best singing performance.
