Over the years, Aeon Zen, in addition to the vocals of Andi Kravljaca and Rich Gray, have enlisted the aid of guest performers such as Atle Petersen (solo artist, Above Symmetry), Nils K Rue (Pagan’s Mind), Michael Eriksen (Circus Maximus), Elyes Bouchoucha (Myrath), Jem Godfrey (Frost*), Andreas Novak (Mind’s Eye), and Jonny Tatum (Eumeria), each adding his own biological and technical distinctiveness to the band’s own.
2013 saw the release of the band’s third album, ‘Enigma’. A departure from previous records, this concept album displayed a band continuing to grow and mature musically while building a solid and increasing fanbase, as well as moving on from early influences like of Dream Theater, Metallica and Opeth, to creating their own unique sound and identity.
Late 2013 saw the release of their Self-Portrait EP, the first release to showcase the stand-alone dual vocal attack of Kravljaca and Gray in 4 tracks re-imagining the band's début album to represent the bands musical and stylistic progression.
In 2014, Aeon Zen released their second concept album, 'Ephemera'. Produced, mixed, and mastered by the band’s own Rich Gray, the album showcased the band’s new line-up with the addition of guitarist Alistair Bell. Continuing the story of Enigma, Ephemera closes the narrative loop with the all-encompassing story of a world reborn.
2019 sees the release of their fifth studio album, 'INVERITAS'. The follow-up to 2014's 'Ephemera' is released on 10th May 2019.
Merging modern metal with complex song structures and a broad range of styles, 'INVERITAS' contains just as many hooks as it is complex, with songwriting always being at the forefront. Also featured are the talents of Vadim Pruzhanov from DragonForce on the album’s title track, showing how different points of view and diverse musical opinions can be used to make Aeon Zen’s strongest statement to date.
Gray continues, "I think all fans of melodic, heavy, technical and progressive metal can find something to love in 'INVERITAS'".
