In 2008, Pete Helmkamp and Gene Palubicki agreed to pursue their musical endeavors and decided to put Angelcorpse on hiatus. Kerasphorus was the result for Pete Helmkamp. Concept-wise, Kerasphorus was composed by P.Helmkamp (bass/vocals) and B.Wolaniuk (guitars) with the intention of creating a sound that allowed all the musical elements to speak with their own voices. Kerasphorus utilized disharmonies and undertones to further enhance its obscure nature.

In 2009, three days of rehearsal and recording with J.Read (session drums) were completed, resulting in the Cloven Hooves at the Holocaust Dawn MCD. Two years later, two days of rehearsal and recording resulted in the Necronaut 12"LP. Both releases received acclaim from fans and press alike. But at the time of the recordings, J.Read and B.Wolaniuk rejected the notion of playing live with Kerasphorus.

In 2016, after much consideration and conversation with Gene Palubicki and Ronnie Parmer, it was decided to make Kerasphorus a facet of Angelcorpse. Angelcorpse has always been described as a black/death band; Kerasphorus is the black-cloaked side of Angelcorpse. G. Palubicki and R. Parmer are now permanent members of Kerasphorus.
