works Three albums by the Dutch composer and multi-instrumentalist Arjen Anthony Lucassen's project Ayreon include guest vocals from Jansen: she sang backing vocals on "My House on Mars" from the album Universal Migrator Part 1: The Dream Sequencer, played the character of Forever, referred to as Ω, (Coincidentally, Jansen used the Ω symbol as an emblem for her band Revamp, and she has the symbol tattooed on her wrist) on seven songs from the album 01011001, and was featured as a character named The Biologist on the album The Source. She is also a member of Lucassen's heavy metal supergroup Star One, and was featured on the studio albums Space Metal and Victims of the Modern Age. She was also featured in the 2018 live album Ayreon Universe – The Best of Ayreon Live. On 9 December 2013, she was also announced as the main vocalist, playing the lead role, for the second full-length album of former Stratovarius guitarist Timo Tolkki's metal opera act Avalon. The album, Angels of the Apocalypse, was released on 16 May 2014. She has also been a guest for the metal band Nightmare. On 22 February 2018, Northward, a hard rock project by Jansen and Pagan's Mind guitarist Jørn Viggo Lofstad, was unveiled. The two created the project in 2007, writing an entire album worth of music in 2008 but being unable to record previously due to their busy schedules; they ultimately reunited in 2017 to finally record the album, which was released on 19 October 2018 under their signed label Nuclear Blast. The album features a duet between Jansen and her sister Irene. In 2019, Jansen participated in the Dutch reality TV show Beste Zangers. In the last episode she partnered with classical singer Henk Poort to perform "The Phantom of the Opera", which was later released as a single. It reached number one on the Dutch single charts, and allowed Jansen to go on a sold-out solo tour in the Netherlands. She also won the Popprijs 2019, a prestigious Dutch award for the artist or band with an important contribution to Dutch pop music in the past year. Among her other performances for Beste Zangers was a solo version of "Shallow", and a separate acoustic duet version of the same song with Tim Akkerman. In 2022, she performed in the German version of Beste Zangers: "Sing meinem Song - Das Tauschkonzert". Personal life
