A month before touring for "Louder Than Love" was to begin, bassist Hiro Yamamoto, who was becoming frustrated that he was not making much of a contribution, left the band to return to college. Jason Everman, formerly of Nirvana, replaced him on bass. The band toured North America from December 1989 to March 1990, opening for Voivod, who were supporting their album "Nothingface", with Faith No More and the Big F also serving as opening acts at the beginning and end of the tour. The band then went on to tour Europe. The band fired Everman in mid-1990 immediately after completing its promotional tour for "Louder Than Love". Thayil said that "Jason just didn't work out." "Louder Than Love" spawned the EP "Loudest Love" and the video compilation "Louder Than Live", both released in 1990.
