In 1990, the band was joined by a new bass player, Ben Shepherd. They released "Badmotorfinger" in 1991. The album brought the band to a new level of commercial success, and Soundgarden found itself amidst the sudden popularity and attention being paid to the Seattle music scene. The band's next album was to be its breakthrough. "Superunknown", released in 1994, debuted at number one on the "Billboard" 200 and launched several successful singles, including "Spoonman" and "Black Hole Sun". In 1996, the band released its fifth studio album, "Down on the Upside"; while successful, the album could not emulate the precedent set by "Superunknown".
