Solo career
In early 1989, Zomba asked Dickinson to produce a track for the movie A Nightmare on Elm Street 5: The Dream Child, providing a budget, a studio, and a producer, Chris Tsangarides. Dickinson took up the opportunity and called an old friend of his, former Gillan guitarist, Janick Gers, and, shortly after meeting up, they had "Bring Your Daughter to the Slaughter" ready for the studio, then recorded with the assistance of bassist Andy Carr, and drummer Fabio del Rio. "I wrote it in about three minutes", states Dickinson, "I don't know where the title 'Bring Your Daughter to the Slaughter' came from, but it just popped into my head. I thought, 'Bloody hell, straight out of AC/DC!' And I thought, 'Nightmare on Elm Street. Yeah, that'll do.' Impressed with the results, Zomba asked Dickinson if he was willing to record a whole album as well. With the same line-up and producer, Dickinson's solo debut, Tattooed Millionaire, was written and recorded within two weeks, and released in May 1990, followed by a supporting tour.
Later that year, Dickinson participated on a re-recording of Deep Purple's "Smoke on the Water", as part of the humanitarian effort Rock Aid Armenia. Backed by the band Skin, he produced a cover version of Alice Cooper's "Elected", along with Rowan Atkinson (in character as Mr. Bean), which was used in 1992 for Comic Relief, and five years later, on Bean Soundtrack.
For his second solo effort, Dickinson received the collaboration of American producer, Keith Olsen, and, while working on the record in LA, decided to leave Iron Maiden. Unhappy with the direction he was taking with Olsen, Dickinson began working with Tribe of Gypsies guitarist Roy Z and started the album again from scratch. Balls to Picasso was recorded with Tribe of Gypsies as the backing band, and was released in 1994. That same year, Dickinson recorded a cover version of "Sabbath Bloody Sabbath" with the band Godspeed for Black Sabbath's tribute album Nativity in Black. Tribe of Gypsies departed to work on their own material and Dickinson tracked down another band, including his new writing partner and guitarist, Alex Dickson. While touring with this new outfit in 1994, Dickinson performed in Sarajevo, then under siege during the Bosnian War; a documentary film based on the concert, titled Scream For Me Sarajevo, completed filming in December 2015.
After the Balls to Picasso supporting tour finished, he started working on a new studio record, Skunkworks. Dickinson decided that Skunkworks would be the title of the band as well, but the record company refused to release the album without his name on the cover. Dickinson hired producer Jack Endino, most noted for producing the first Nirvana album. The "Skunkworks" entity ceased to be when the tour ended. "I was devastated by the Skunkworks thing", stated Dickinson. "Skunkworks was a record which I tore myself apart to make and nobody seemed to give a shit."
After a short period of inactivity, Dickinson once again teamed up with Roy Z and Tribe of Gypsies to record his next album, Accident of Birth; "It was actually Roy that dragged me back into some assemblance, because he called up and he said, 'Listen, I've got some stuff and it's like a metal record.' And I wasn't thrilled, I wasn't really sure that I had anything to offer ... Then he played me some backing-tracks he'd done for what was to become Accident of Birth down the phone and I thought 'There is something there.'" Former Iron Maiden guitarist, Adrian Smith, was asked to guest on the record, but remained as a full-time member of Dickinson's solo outfit. The album marked a return to heavy metal for Dickinson, with Sputnikmusic remarking, "The album's heavy feel is very satisfying, and definitely fills that void left by Maiden during the 90's." The follow-up, The Chemical Wedding, was a semi-concept album on alchemy, which drew inspiration from William Blake's writings; with some songs, such as "Book of Thel", having the same title as some of his poems, and the cover artwork featuring one of his paintings. The record was even more successful than its predecessor, with Sputnikmusic commenting: "Bruce had shattered all expectations to create an album that might even be better than the previous one." During The Chemical Wedding's supporting tour, the live album, Scream for Me Brazil was recorded in São Paulo, after which Dickinson and Smith returned to Iron Maiden in February 1999.
In 2000, Dickinson performed vocals on the song "Into the Black Hole" for Ayreon's Universal Migrator Part 2: Flight of the Migrator. Later that year, he collaborated with Judas Priest front-man Rob Halford, recording "The One You Love to Hate", for Halford's debut, Resurrection. A compilation, titled The Best of Bruce Dickinson, was released in late 2001, including two new songs and a bonus disc of rarities. His sixth solo album, Tyranny of Souls, was released in May 2005. This time the song-writing was split between Roy Z and Dickinson and many songs were composed by Z sending recordings of riffs to Dickinson while he was on tour with Iron Maiden. On 21 June 2005, Dickinson's complete solo discography was re-released, featuring bonus discs with rare and remastered tracks. That same year, Dickinson contributed to the song "Beast in the Light" from Tribuzy's album Execution and their subsequent live album. A three-DVD box set, titled Anthology, was released on 19 June 2006, containing concerts and promo videos from throughout his solo career, as well as an old Samson video, titled "Biceps of Steel".
A fan of the Monty Python comedy troupe, in 2009 Dickinson appeared in Monty Python: Almost the Truth (Lawyers Cut). He also recorded a new version of the theme song from Monty Python's Life of Brian for the sixth and final episode. In December 2017, Dickinson said that he has tentative plans for his next solo album to be "a whole concept album", with the title being If Eternity Should Fail, the same song name from Iron Maiden's album The Book of Souls, in which he confirmed that it was originally penned as a solo track. "So if I did do another solo album, which I think I will, I might just stick to my original plan and have that as the title track. I mean, I did write it – it was the first track that I wrote for it. So, yeah, I'd probably still include that song. But it would be... the feel would be slightly different – not very much, though – from the Maiden version." Dickinson released The Mandrake Project, his first solo studio album in 19 years, in March 2024. It was produced by Roy Z. The record saw commercial success and peaked in the top 10 in multiple countries and No.1 in German and Austria. It also received critical success. Blabbermouth.net stated: "The Mandrake Project" is magnificent, mandatory listening for fans of heavy metal."
In June 2025 Dickinson released a remaster of his 1994 album Balls to Picasso called More Balls to Picasso. The record also included previously unreleased live in-the-studio tracks 'Gods of War' and 'Shoot All the Clowns'. Dickinson also embarked on his first solo North American tour in 30 years in support of his album The Mandrake Project, which went from August to October. He also announced that he will begin recording his new album, which he plans to have finished by 2027.
