Ulver

1997's Nattens madrigal with Aismal and Skoll back was a return to business as normal. This album was more raw and basic than the debut, with lyrical themes based entirely on wolves as well as the album titles. The album received international exposure through German label 'Century Media'. However, following discord with the label, Rygg formed his own imprint, 'Jester Records', by the following year.

After the release of their 1997 box set, The Trilogie: Three Journeyes Through the Norwegian Netherworlde, all of a sudden, and in one of the most drastic changes in style in heavy metal history, Ulver were no longer a black metal band with their release of Themes From William Blake's The Marriage Of Heaven And Hell (1999), the title alone leading one to question the contents. A new position had been added to the band in the form of Tore Ylwizaker on programming. Indeed, their Metamorphosis EP was a very appropriately titled release that continued along these lines and was exclusively a production of Rygg and Ylwizaker. With 2000s Perdition City their transformation from a black metal band was complete, as not only was their black metal past just that - the past, but so was much of their relation to heavy metal at all! Ulver was now diving deep into the pools of electronica and hip-hop and other ambient forms of music.

Silence Teaches You how to Sing EP (2001) featured only one long track and added member Jørn H. Sværen filling in on miscellaneous instruments needed, that was followed by Silencing the Singing EP (2001), two releases featuring titles that snubbed the nose at those who failed to accept their changes.

The experimentation would continue with Lycanktropen Themes (2002; soundtrack of short film Lycanktropen), A Quick Fix of Melancholy EP (2003), Svid Neger (2003), Teachings In Silence compilation (2003), and a release of both Silence... EPs compiled titled 1993-2003: 1st Decade in the Machines (2003). Blood Inside (2005) and Shadows of the Sun (2007).

For Wars of the Roses (2011), Daniel O'Sullivan had joined on guitars/bass/keyboards/narration.

Childhood's End (2012) was a reinterpretation of '60s psychedelia intended by Ulver as a reflection on lost innocence. Messe I.X-VI.X (2013), ATGCLVLSSCAP (2016) and Riverhead (Original Motion Picture Soundtrack) (2016) followed. Ole Aleksander Halstensgård provided additional various instruments for The Assassination of Julius Caesar (2017).

The EP Sic Transit Gloria Mundi (2017), the live set Drone Activity (2019), Flowers of Evil (2020) and Scary Muzak (2021) followed. 2023 would see the release of another live album in the form of Grieghallen 20180528.
