song that could be credited to one person”. According to Turner, the album's inception and sound were organic, rather than engineered: “[w]e were interested in exploring ambient spaces a lot more—and these things tend to dictate a longer structure. It wasn't a conscious decision on our part; I guess it's just the nature of the style we write in.” After having worked with members of 27 as guest musicians on previous full-length Oceanic, for Panopticon Isis turned to Justin Chancellor, bassist of tour-mates Tool.
