Iommi is the debut solo album by British heavy metal and Black Sabbath guitarist Tony Iommi. The album took nearly five years to make. All of the songs were written by Iommi, producer Bob Marlette and the respective vocalists of each track (except "Black Oblivion", which was written by Iommi and Billy Corgan). According to Iommi, he and Phil Anselmo had recorded three tracks together for the album, but only one was put onto the album. Iommi has also said he "wrote a couple of tracks with Billy Idol and two with Billy Corgan, but you know, we could only use one of each".
