In 1990, the band was joined by a new bassist, Ben Shepherd. After this, Soundgarden's line-up would not change until their break-up. In 1996, the group became unhappy while recording "Down on the Upside". Thayil and Cornell seemed to not agree on a change from the heavy guitar riffs that had become the band's trademark. In 1997, the band broke up. They had not been getting along during the past half year.
