and also gave a concrete release date of June 9, 2015 for Cauterize. On March 20, 2015, Tremonti unveiled via Twitter that the first single, titled "Another Heart", was released March 24, 2015. On March 23, 2015, the single Another Heart was made available for streaming via fret12. On March 27, 2015, the artwork for Cauterize was revealed and it was revealed that Cauterize was the first of two albums to be released as the two albums were recorded together. "The second album titled Dust will be released in early 2016, "after [they] record the Alter Bridge record and [they] have that three or four month gap, [he]'ll be looking to tour on it to support it." Tremonti said he "wanted to make sure both albums flowed dynamically. If there were two slow moody songs, [he]'d put one on each album, same thing if there were two really heavy aggressive songs, [he] would split them up evenly. There's isn't a specific theme to one or the other. Each record is mixed" and that "it's definitely not the 'b-sides' of this album." Dust was released on April 29, 2016, via FRET12 records, and produced by Michael Baskette who produced Tremonti's past two records and has also produced most of Alter Bridge's records. Tremonti's fourth solo album, the concept album A Dying Machine, was released on June 8, 2018, via Napalm Records. The record was once again produced by Michael Baskette. The album is accompanied by a full-length novel under the same name written by Mark Tremonti and John Shirley, tying together loose ends of the album's plot. Tremonti supported Iron Maiden on the European leg of their Legacy of the Beast Tour in June 2018. Other works Tremonti has worked with several artists since his beginning years with Creed. In 2001 he collaborated with comedian Larry the Cable Guy on his comedy album Lord, I Apologize, on which Tremonti is credited as a performer and songwriter. Tremonti later recalled, "We had become friends a long time ago, before his career really started to take off. We joked about getting together and doing a song, and he called me up one day to say he actually wanted to do it. So he sang me his idea, and I went to record my guitar lines that day, and the record went gold." Tremonti later began performing in the neo-classical metal genre with guitarist
