Bands like PFM, King Crimson, Gentle Giant, Yes, Museo Rosenbach, ELP and so on were highly influential on the group.
By now, Lars Fredrik Frøislie's vintage keyboard collection had grown and the recording of Hinterland began in June 2004.
In July 2005, Hinterland was revealed at NEARfest in Bethlehem, Pennsylvania, one of their rare live performances.
[4] Although the album's niche genre resulted in limited exposure in some parts of the music press, it received reviews ranging from favourable to rapturous on Angry Metal Guy,[5] The Prog Space,[6] Prog Report,[7] Prog Radar,[8] Team Rock,[9] and many others; Sonic Perspectives[10] and The Fire Note[11] ranked it as the best progressive rock album of the year, while the Norwegian website Evig lyttar ranked it as the best Norwegian album of the year.
Band members Prestmo, Kneppen, and Frøislie collaborated with other Norwegian prog artists on the long-running project The Chronicles Of Father Robin which released three volumes of The Songs & Tales of Airoea in 2023 and 2024, initially as a crowdfunded box set, and later via individual releases on Karisma Records.
