Allen/Lande is a collaborative metal supergroup project formed in 2005 by Symphony X vocalist Russell Allen and former Masterplan vocalist Jørn Lande. They were formed under the Italian record company Frontiers, with Swedish guitarist Magnus Karlsson serving as producer, main instrumentalist, and songwriter alongside drummer Jaime Salazar. Their debut album The Battle was released in 2005, followed by The Revenge (2007) and The Showdown (2010). In 2013, Timo Tolkki and Jami Huovinen replaced Karlsson and Salazar, leading to the release of The Great Divide (2014). In 2019, Lande announced there would be no more Allen/Lande albums, and Allen went forward with another collaboration, Allen/Olzon, featuring former Nightwish singer Anette Olzon. Their discography includes the albums Worlds Apart (2020) and Army of Dreamers (2022).
