Ulcerate is a New Zealand-based extreme metal band formed by guitarist Michael Hoggard and drummer Jamie Saint Merat in 2000. The band have released six studio albums to date. The band have been featured in numerous articles as one of New Zealand's most prominent extreme metal acts, have toured widely across North America and Europe, and have been compared favourably to bands such as Neurosis and Gorguts. The band's sound has been described as "nauseating, disorienting and gleefully disharmonic", and is characterised by extremely technical death metal with extensive use of dissonance, time signature changes, and complex song structures.

Gorguts is a Canadian death metal band formed near Sherbrooke, Quebec, in 1989. The band has gone through various membership changes since its inception; its only constant member has been guitarist-vocalist and co-founding member Luc Lemay, who remains the driving force of the band. To date, they have released five full-length albums and one EP. Their most recent release, Pleiades' Dust, was released on May 13, 2016. Their latest full-length album, Colored Sands was released in 2013 and was nominated for a Juno Award. Musically the band is known for its complex, musically dense form of technical death metal, and has become "one of the most advanced, experimental, and challenging groups in the entire genre."
