Inocula have been swapping in and out members while fusing elements of metalcore, progressive rock/metal, melodic death metal, and electronica since 2005. The base of the band has been Chris, Dan, Paul, and Tyler. The singers and drummers have just been a revolving door and the band is on their third each for their debut record Suntelia Aeon. Once this line-up was determined, the band took seven months off from playing any songs and wrote this record. Once they were done, they tapped Cory Smoot (Flattus Maximus of GWAR) to produce the record.
