Work began on his debut album Bitter Pill album in 2015. It was recorded in London and LA with Producers Fraser T. Smith and Cam Blackwood. James on the album, "I've always wanted to hear how my songs would sound properly produced, but I didn't want them to lose the edge they had live. We recoded the song Bitter Pill first and once we found the sound for that the rest was easy."

Как автор песен и продюсер, Андре Таннебергер (Andre Tanneberger) в течение достаточно долгого времени живёт в двух мирах. Первый –– это мир электронной музыки, в котором он создал немало экстраординарных, мелодичных, клубных композиций и отыграл бесчисленные ди-джей сеты по всему миру. Его творения –– "The Fields of Love", “9 PM (Till I Come)”, “Don’t Stop”, “Killer”, “Let U Go” и “Ecstasy” стали настоящими хитами, благодаря им Андре получил международную известность и признание. Второй мир –– это атмосферная область, более спокойные, воздушные треки, слушая которые вы растворяетесь и начинаете мечтать.

Arcturus have indeed delivered an album that is up to the challenge of the times, only not so overtly. It's more of a culminative example of what has been perfected in the fields of progressive/somewhat symphonic black metal. It is more varied, both melodically, rhythmically and in timbre, that any of its predecessors. Also, while Hellhammer continues to be Hellhammer, there's a noticeable maturity and subtle change of style to the riffs and execution. One can only marvel, for example, at a man like Vortex, who, to allude to the proverbial wine, seems to be today at the top of his game, jumping from the harshest, most vitriolic shrieks he's ever uttered, with his now trademark playful and precise quasioperatic singing.
