Possession's message board that Matthew Chalk (ex-Psycroptic, Mephistopheles) and Christian Muenzner (ex-Obscura, ex-Necrophagist) have joined the band. Bryssling states "Two very talented and competent musicians has recently joined Spawn of Possession. Matthew Chalk (Ex-Psycroptic) is going to handle the vocal and lyric writing. Christian Muenzner (ex-Obscura, ex-Necrophagist) is going to do the Lead Guitar part and unleash his madness into the multicoloured and distorted universe of Spawn of Possession. The Line-up is now complete." In the same year, Norwegian bassist Erlend Caspersen (Blood Red Throne, The Allseeing I), known for his highly technical playing, also joined the band to complete the lineup. However in September 2010, Dennis Rondum joined back and will handle the vocals instead of Chalky who just joined for a brief period. In December 2010, Richard Shill has been relieved from drumming duties. The reason cited was that Richard depends very much on actual band practice and with SoP members being scattered all over Sweden, Norway and Germany band practice becomes an impossibility. Henrik Schönström announced as new drummer. On March 13, 2012, with three new members, Spawn of Possession released their third retail album, Incurso, which was met with very positive reactions from fans and critics alike, being their most technical and heavy record up to date. It is often being dubbed as 'one of the most influential modern death metal records, next to Necrophagist's Epitaph and Obscura's Cosmogenesis, all of which Muenzner performed on. However, most of the music was written by Jonas Bryssling with assistance of Erlend Caspersen on certain songs. On August 4, 2017 the band announced on Facebook they were breaking up, stating: Influences Spawn of Possession have been influenced by many different artists from various subgenres, mainly from death metal and classical music. They have been influenced by artists such as Death, Monstrosity, Nocturnus, Morbid Angel, Suffocation, Cannibal Corpse, Gorguts, Dismember, Edge of Sanity, and Carcass as well as art music composers such as Johann Sebastian Bach, Sylvius Leopold Weiss and Dmitri Shostakovich.
