The musical styles of Imaginary Sonicscape further explored the experimental tendencies of the band's previous album Scenario IV: Dread Dreams with further psychedelic elements to the band's sound. While the band's new sound was influenced by jazz, classical music and Frank Zappa, the lyrics of the album were based on the band's views on life and death. Band member Mirai described it as "Most of the lyrics on the album are about life and death and fear of getting old, fear of losing somebody you love." The style of the album draws from many genres outside of the extreme metal sound, occasionally drifting into sounds ranging from dub, giggling babies, jazz fusion and disco. Frontman Mirai explained that the band "never intend to make it musically varied or weird. I always choose the best way to express the feeling. Sometimes it could be heavy guitars while sometimes it could be a classical piano solo. And as a result, sometimes the song has lots of different elements. It's just a result, not a purpose."
