Kohllapse is a gothic and progressive doom metal band from Canberra, Australia, formed in the early 1990s. They were one of the better-known Christian gothic-metal bands active in the 1990s, and were closely followed by the newsportals of the scene throughout the band's career.

While Kohllapse released its only two albums independently, their catalog was distributed widely through Nuclear Blast USA and Blast Beats distribution. The band is notable for its innovative music, a combination of progressive doom metal and darkwave which was said to be ahead of its time, and because the band became significantly well-known in both secular and Christian metal scenes. Distant Mind Alternative was their most popular and critically acclaimed album, and has been re-issued by Soundmass in 2005. The band mainly consisted of guitarist-vocalist Ro Edwards and drummer-keyboardist Matt Aitchison. After Aitchison left in 1999 the band split up in 2001. In 2005, Edwards indicated in an interview that he's working on a third Kohllapse album.

Kohllapse was formed by guitarist-vocalist Ro Edwards and drummer-keyboardist Matt Aitchison in the early 1990s as a death metal band. By mid 1990s, just like many other former death metal groups, Kohllapse began developing their sound away from its roots to more experimental direction.

In the year 1995, the band began independently recording its first album, originally intended as a promotional cd. The band released Kohllapse in 1996. It was noted for its exceptionally dark and varied sounds that combined death, doom, gothic and electronic elements. One song, "An End to Pain" features black metal type output. Kohllapse was chosen as the "Pick of the Litter" in HM Magazine March-April issue in 1997, and was described as "the first Christian band that sounds like Type O Negative". The song "Tell Me Your Fears" was released on the magazine's sampler in 1998.

After the release, the Christian metal scene press began to follow the band's career, and reported any updates given in interviews or Kohllapse's website. Since Kohllapse are an Australian band, the European and United States labels were uncertain whether to sign the band, and the Australian labels couldn't sign a studio-project group, thus the band remained unsigned. However, they got a distribution deal with a Texas, United States based Blast Beats music seller, which distributed the album further. The album received positive notice: in 1997 they began receiving major label interest, and in 1998 the band signed a distribution deal with Nuclear Blast USA.

This distribution deals helped Kohllapse to reach new fans all over the world. During this time, few bassists joined and left the band, Bevan Carroll was one of them. It remains unknown whether Kohllapse ever played concerts in the local scene of Canberra. Around 1998, it was reported that the band went through "very rough times", while details of this were never revealed.

In 1999, Paul Sweeney joined as a bassist, and the band recorded and released Distant Mind Aternative, their darkest, most doom oriented, and most atmospheric album. The album introduced a more mellow and somber direction with more emphasis on dark electronic sounds. Edwards switched his vocals to deeper baritone singing in contrast with the previous death grunt style. Distant Mind Alternative was distributed through Nuclear Blast, and achieved rave reviews and critics called it innovative for its style that combined darkwave with doom metal. Anne Marootians did some female vocals on the song "Contort". A music video was shot for "Thorn", and was released on Heaven's Metal Video Magazine Volume 6 VHS. Soon, underground magazines began to call Kohllapse as one of the big names in Australian doom scene together with Paramaecium and Avrigus.

However, Aitchison left Kollapse after the release.

According to Edwards, after the release of Distant Mind Alternative, some notably large secular labels showed serious interest towards Kohllapse, but since Aitchison had left at a crucial point in the bands career, to pursue his own musical interests, the band couldn't sign a contract.

After 2 years of silence, Ro Edwards officially announced the end of Kohllapse in 2001. He mentioned about starting a project called "Dead Sea", which would focus on a far more electronic style than Kohllapse. However, later in an interview Ro stated that he had recorded only two songs for Dead Sea, and left Dead Sea as an inactive project.

In 2005 the Australian label, Soundmass, reissued Distant Mind Alternative. Afterward, it has been recognized as a masterpiece.
