During the same year, G-Stealer left the band because of work commitments and was replaced by Magnum, whom Mr Lordi had met via Kiss Army Finland.

[4] In 2003, Lordi appeared at several music events in Finland and abroad, especially in Germany, where they played as a part of the Wacken Road Show.

Sanctuary had originally intended to market a collection of records in the United States, but these plans were halted due to financial problems.

The idea of The Monster Show disc collection has its roots in the spring of 2004, around the release of The Monsterican Dream album.

Mr Lordi tried to persuade Kalma to stay and suggested that he just play the biggest tours and other contractually obligated performances.

Pasi Rantanen from the band Thunderstone performed backing vocals, wearing a Gene Simmons Kiss mask.

The tour ended with a surprise: during the last gig in London, on 31 October 2006, the band's former bassist, Kalma, was seen as a guest on stage.

[11] At the end of the tour the band returned to Finland to record the theme song, "Beast Loose in Paradise", for the 2008 film, Dark Floors.

[15] The album was similar in style to its predecessors, melodic hard rock and heavy metal, though with more of a horror theme.

[17] Lordi performed "Bite It Like a Bulldog" on the NBC show Late Night with Conan O'Brien on 6 November 2008.

[18] Mr Lordi spent a week in Los Angeles with Jeremy Rubolino and former Kiss guitarist Bruce Kulick writing two new tracks, "Cut Off My Head" and "Call Off The Wedding".

In 2011 Mr Lordi took part in Finnish TV-series "Kuorosota"[22] and because of that reason the band could not make a long tour.

[25] Lordi began recording their sixth studio album on 1 September 2012 with two new members, Mana as the new drummer and Hella as the new keyboardist.

On 27 February 2016, Lordi performed "Hard Rock Hallelujah" in the Finnish Eurovision final, as special guests.

[34] Lordi announced the title of the eighth album, Monstereophonic (Theaterror vs. Demonarchy) on 13 July, which was released on 16 September.

[39] Following four festival shows in the summer, a tour in support of the album called "Sextourcism" began in Europe on 9 October in Amstelveen, Netherlands and concluded on 28 December in Helsinki, Finland.

"[55] On 19 August 2021, the band released their single "Believe Me",[56] and simultaneously announced Lordiversity, a box set that consists of the band's eleventh to seventeenth studio albums: Skelectric Dinosaur, Superflytrap, The Masterbeast from the Moon, Abusement Park, Humanimals, Abracadaver, and Spooky Sextravaganza Spectacular.

[63] Mr Lordi released a statement the following day regarding this, clarifying that he had asked Amen to leave the band at the end of February 2022 due to growing tensions.

[75] On 29 June 2024, Mr Lordi confirmed in an interview with Chaoszine that their upcoming nineteenth studio album was already finished, and is set to be released in Spring 2025.

Over the years, the band's musical style has taken a very varied direction between hard rock and metal, with the pattern seeming as though it changes between the two with every album released.

However, in their 2006 album The Arockalypse, Lordi shifted back toward hard rock, eschewing horror themes and special effects.

Their 2008 studio album, Deadache, included more typical horror elements, leaning once again toward the heavier side of the spectrum.

Their 2014 album, Scare Force One, contains elements of heavy metal while still maintaining the melodic rhythm of hard rock.

[4] The monster masks and costumes the band use are made of foam latex, with some other materials like canvas, metal and leather.

[4] The monster costumes are such an integral part of Lordi's publicity image that they refuse to be photographed or even interviewed without them, even if in some cases it leads to their own discomfort.

In a brief segment on the BBC reporting about the band attending the Eurovision Song Contest 2006, they were shown lounging beside a pool in full sunlight, while wearing their monster costumes.

On 15 March 2006, the Finnish tabloid Ilta-Sanomat published a photograph of Mr Lordi in civilian clothing, with his face partially showing.

After a few seconds, Heikki Paasonen (the Eurovision Finnish commentator) in a black Lordi shirt came and stood in front of the camera, covering the view.

Itella, the Finnish postal service, issued a Lordi postage stamp in May 2007 in recognition of their Eurovision win.

[88][89] The restaurant expanded to the Rinteenkulma shopping center in 2008, but closed in 2011 after its rental contract ran out, having reportedly been in financial difficulties the previous year.
