He was credited on the albums Leprosy and Spiritual Healing, and band leader Chuck Schuldiner stated that on the latter album "Terry contributed to the songwriting as well". Before he joined, he was in with Rick Rozz, whom he played with in Leprosy-era. In an interview, Butler has stated: "I"d rather be popular in the underground, than be unknown in the mainstream." In late 2011 it was announced that Butler was reforming with former bandmate Rick "Rozz" DeLillo, with the intention of securing a record deal, recording a new album, and international touring.
The band performed on the cruise ship "70,000 Tons of Metal" in January 2012 and subsequently signed a worldwide recording agreement with Century Media Records.
Terry has also agreed to join the all star guest list on the upcoming Vegas Rhythm Kings album Barrel O" Zombies.
