In 2014, Lande was hired by Riot Games to be the voice of the character Karthus, of the fictional heavy metal band Pentakill (League of Legends).

Later on, Jørn got together with guitarist Tore Østby (Conception) and drummer John Macaluso to form the progressive metal band Ark and record their first self titled album in 1999.

Right after in 2000, he also made part of the American hard rock band Millenium, led by guitarist Ralph Santolla, and recorded the vocals for their album Hourglass.

In 2002, Jørn joined the melodic power metal band Masterplan, formed with Roland Grapow and Uli Kusch after both were fired from Helloween.

Jørn released two successful albums with Masterplan, playing at big festivals and tours around the world from 2003 to 2006 until he left the band on 11 May 2006, because of creative differences.

[6] The project is commonly called Allen-Lande and was put together by the president of Frontiers Records, with songwriting duties and most of the instrumentation done by Swedish guitarist Magnus Karlsson.

In late May, a Jorn music video honoring legendary heavy metal singer Ronnie James Dio, who had died of stomach cancer just five days before, was posted on YouTube.

[9] Later on, it was announced that Jørn was included in the line up of Heaven & Hell, when the remaining members played the one off tribute to Ronnie James Dio at the 2010 High Voltage festival.

[17] Jørn Lande also announced in an interview that a new Allen/Lande album was in the works but this time with songwriting and production made by former Stratovarius guitarist Timo Tolkki, replacing Magnus Karlsson.

[19] In 2014, Lande provided lead vocals for songs Lightbringer and Thornmail for the fictional League of Legends band, Pentakill (named after the rare occurrence of one player defeating all five of the enemy team in quick succession) taking the role of Karthus, a lich that serves as one of the playable characters in the game.

[20] The same year, it was announced a project created by Lande together with guitarist Trond Holter (former Wig Wam), an album rock opera based telling the story of Bram Stoker's Dracula.

[25] In 2016, Jorn announced a new release called Heavy Rock Radio, his third album consisting only of covers songs from artists that inspired him to start a musical career.

This time the album would include covers from pop artists such as Kate Bush, Frida, John Farnham and also some rock icons such as Paul Stanley, Queen, Iron Maiden, Journey, Eagles and many more.

[28] He also performed live once again with the band in Brazil during the CBLOL (League of Legends Brazilian Championship) 2017 edition grand final, in the city of Belo Horizonte.
