After a 1996 Lollapalooza tour and an ensuing world tour, internal tensions lead to the band calling it quits in 1997 (they would reunite for 2012’s well-received King Animal and continue to tour until Cornell’s death). On 1996’s Down on the Upside, the band moved away from their heaviness of their previous releases and began experimenting with a more psychedelic sound. 1994’s Superunknown took Soundgarden to even greater heights: The album became their only studio LP to top the Billboard 200, and all five singles charted on the Alternative Songs chart – of those songs, “Black Hole Sun” and “Spoonman” are all-time rock classics.
