 Even though the surviving members of Sublime (Eric Wilson and Bud Gaugh) stated that the band would not make any more albums after Nowell's death, which would result in the band's breakup, MCA bound them by their contract and made the remaining members follow out their contract with the next 3 albums.
 Instead of recording more albums with Sublime, Wilson and Gaugh would record together in their later projects Long Beach Dub Allstars and Sublime with Rome.
