Kamil “Wrathu” Kwiatkowski was born in Gorzów Wielkopolski (Poland). He composes experimental electronic music which he publishes since 2009. He touched many different genres such as dark ambient, post rock, industrial, darkstep, dnb, trip hop, instrumental hip hop. But he’s still searching for new solutions and likes to collaborate with other musicians. He’s inspired by such artists as Nine Inch Nails, Rammstein, Linkin Park, Mark Morgan, Coil, Lustmord, Björk and others. He made his debut in the Internet thanks to the online magazine Trzynasty Schron (Vault 13) about postapocalypse in culture where he became an editor. For composition he uses mostly software and plugins (FL Studio, Nexus2) and for concerts he plays a MIDI keyboard E-mu xboard61. In 2015 he began his collaboration with the ambient guitarist Sebastian Siuda (Mała Fuzja) as Wrathu + Mała Fuzja. They were awarded with a consolation prize at Getting Out 2015 and were given a grant from the president of Gorzów Wielkopolski in 2016 for their artistic needs. They played in four voivodeships, mostly Lubush Voivodeship. In Zielona Góra, a beatboxer Zgas performed “Inside” with them. In Żagań they supported a Polish industrial rock band Agressiva 69. Wrathu + Mała Fuzja recorded “The Nihilist” (2015, promoted by songs “Amoralism”, “Hypocrisy”, “Home” and “Tides”) and “Entropia” (Polish word for "Entropy") which was the first one with vocals (promoted by "The Maze" and "Contemporary Pagan"). Moreover, since 2009, Wrathu recorded seven solo albums, e.g. “Sólin” (2016, promoted by “Jörðin”), inspired by Iceland, much calmer than dark and pessimistic “The Nihilist”. “Sólin” (Icelandic for the Sun) has been described by Moll Płytowy as “deep alternative mixed with chillstep”. Sebastian Gabryel in a review described Wrathu’s music as remarkably emotive, resembling Icelandic experimental music, evoking such artists as Björk, Sigur Rós or múm. This is the album from which “Freyja” is from. During the performance of this song in Cigacice a thunder ended the concert. Since then, they always play this song up to this particular moment and there are audio samples of a storm in the album version. Wrathu, inspired by ambient and dark ambient, composed also soundtracks for Polish off films, e.g. postapocalyptic “Powód” (The Reason). He edits his music videos on his own. Sometimes, he used excerpts from films by the Polish cult off film group Sky Piastowskie. After the last album he took part in a compilation “…Części Ciała, Fragmenty Duszy” (2017) by recording “Human Trees” with lyrics being a translated poem by Jacek Katos, recorded by Maciej Niedzielski at Exe Laboratories. He also contributed to an American electronic compilation “(Insert Comp Name Here) Vol. 02” (2018). In 2022 he published an album with Testral, Wound Roots (promoted by "Pain Go Away" and "Graduation Day") as Wrathu + Testral. They also contributed to an international compilation Discordance I coordinated by Wrathu. Since 2023 Wrathu is available on Spotify and other streaming services.
