Jonas Petter Renkse (born 19 May 1975) is a Swedish musician in the bands Katatonia [2] [3] (1991–) as lead vocalist, founder, songwriter (1991–1994, 1997–) and formerly as drummer (1991–1994, 1996–1998); in Bloodbath [4] (1998–) as bassist, founder, songwriter; and in Wisdom of Crowds (2013–) as co-vocalist.


He was also the founding member, drummer, vocalist, guitarist & songwriter of the band October Tide. [5]


In 1995 Katatonia was put on a halt due to not having a suitable lineup, and Renkse subsequently decided to form October Tide.

In 1996, Jonas' performance of death vocals had taken such a toll that by 1997 he would only sing cleanly. By 1998, Renkse decided he would focus strictly on vocals and abandon drums.

Renkse wanted to guest on The Ocean's album, Precambrian but due to Katatonia's touring schedule during the production, The Ocean was not able to approach him on time. He would later appear on the track "Devonian: Nascent" off of their 2018 release Phanerozoic I: Paleozoic, as well as "Jurassic | Cretaceous" from the 2020 release Phanerozoic II: Mesozoic & Cenozoic.

Personal life

Renkse has three children, [6] and is best friends with singer Mikael Åkerfeldt of the band Opeth. [7] [6] Åkerfeldt recorded part of the Blackwater Park album at Renkse's house. [8]

Opeth Swedish progressive metal band

Opeth is a Swedish progressive metal/rock band from Stockholm, formed in 1989. The group has been through several personnel changes, including the replacement of every single original member. Lead vocalist, guitarist and songwriter Mikael Åkerfeldt has remained Opeth's primary driving force since the departure of original vocalist David Isberg in 1992. Opeth has consistently incorporated progressive, folk, blues, classical, and jazz influences into its usually lengthy compositions, as well as strong influences from death metal, especially in their early works. Many songs include acoustic guitar passages and strong dynamic shifts, as well as demonic vocal characterization. Opeth is also well known for their incorporation of Mellotrons in their work. Opeth rarely made live appearances supporting their first four albums, but since conducting their first world tour after the 2001 release of Blackwater Park, they have led several major world tours.

Katatonia Swedish metal band

Katatonia are a Swedish metal band formed in Stockholm in 1991 by Jonas Renkse and Anders Nyström. The band started as a studio-only project for the duo, as an outlet for the band's love of death metal. Increasing popularity led them to add more band members for live performances, though outside of the band's founders, the lineup was a constantly changing, revolving door of musicians throughout the 1990s, notably including Mikael Åkerfeldt of the band Opeth for a period. After two death/doom albums, Dance of December Souls (1993) and Brave Murder Day (1996), problems with Renkse's vocal cords coupled with new musical influences led the band away from the screamed vocals of death metal to a more traditional, melodic form of heavy metal music.
