As a son of two musicians, Linus Klausenitzer was faced with music at a very young age. Before he found his passion in playing the bass when he was 15 years old, he learned to play piano and trumpet. After graduating at a musical secondary school, he studied at the music college in Regensburg and graduated from a study course in popmusic at the conservatory in Hamburg. Having gained experience in bands of several genres, the German bass player found his main place in the genre that he has always loved most: Metal Music.

He started to perform internationally as a band member of Fall of Serenity and his first experimental band Noneuclid.
After recording their masterpiece “Metatheosis” Noneuclid’s pioneering spirit led to an appearance in the renowned contemporary music festivals “Dag in de Branding” (Den Haag) and “Dutch Music Days” (Amsterdam), where the band premiered the 25-minute death metal symphony “Black Vortex Cathedral” as soloists along with the world famous “Dutch Metropole Orchestra“, in front of a stunned classical audience in the fall of 2008. In 2010, the band embarked on their next symphonic collaboration, this time with Linus’s father Professor Ulf Klausenitzer’s “Bavarian Chamber Orchestra“: “Transition Metal”, an encounter between the music of Richard Wagner and Noneuclid.

In 2011 Linus Klausenitzer joined the German band Obscura. Linus started extensive touring on multiple world tours with such renowned artists as Sepultura and Children of Bodom. Later Obscura started to play headliner tours in Europe, Australia, Central/North America (USA, Canada, Mexico) and Asia (Japan, United Arab Emirates, Thailand, Singapore, Indonesia, …).

In 2014 Linus co-founded the extreme metal band Alkaloid which consists of international high-class musicians, including current and former members of Obscura, Spawn of Possession, Aborted, Dark Fortress, Necrophagist, God Dethroned, Blotted Science and Noneuclid. Alkaloid seamlessly ebb and flow through an arrange of styles and genres, creating an intelligent and fascinating blend of Prog, Death Metal, and Fusion. In 2015 Alkaloid was the first German Death Metal band to ever perform in Egypt.

In April 2020 guitarist Rafael Trujillo, bassist Linus Klausenitzer and drummer Sebastian Lanser decided to move on from the band Obscura and continue their musical path with their new band Obsidious

Linus Klausenitzer regularly gives bass masterclasses (“Guitar Summit”, “Popakademie” and many more) and is a speaker about topic “a digital musician”. Digital masterclasses are available at different online platforms like and

As a studio artist he recorded with musicians like Marco Minnemann (Steven Wilson, Joe Satriani, Kreator, etc.), Jeff Loomis (Arch Enemy, Nevermore) and Marty Friedman (Megadeth). 


In April 2020 guitarist Rafael Trujillo, bassist Linus Klausenitzer and drummer Sebastian Lanser decided to move on from the band Obscura and continue their musical path with the new band Obsidious. The name comes from the volcanic stone obsidian, which is heavy and dark, but has a lot of fine details. All three members are known for their high musicianship and virtuosity. Their advanced technical level is an essential and unique part of their compositions. Guitarist Rafael Trujllo has a multicultural background and studied music in different countries all around the globe. Strong drum independence skills and stylistic diversity make Sebastian Lanser one of the most influential drummers of the new generation.

They built a strong bond after years of touring and recording together with Obscura especially since the production of the last record “Diluvium” that hit the charts worldwide. The decision to split from Obscura was made to enable the trio to move on and continue to take the quality of their musicianship to the next level. Their music consists of modern riffs, strong decisive energetic melodies, virtuous and epic unison lines.

This band is defined through the field of tension created between musical opposites. ALKALOID merge extreme metal and other more diverse genres of music into a unique style that people will somehow find familiar, but haven‘t heard yet.

All musicians in the band are known and active death metal players who all have a much broader view of music than just blastbeats and growls. Alkaloid want to establish from the beginning that they have many faces, and oscillating between (seemingly) contrary or mutually exclusive styles is a factor. To use playing technique only to write good songs, is another factor.

Alkaloids are a chemical compound produced by many plants and other organisms.
They are found in many psychoactive substances (psylocin / LSD, cocaine, nicotine, caffeine, morphine, bufotenin, and many medical plants among others). The band sees the term Alkaloid as a symbol for the chemical agent that changes matter, or the perception of the physical universe and produces intense experiences of a multidimensional or exaggerated nature. The fact that they affect both mind and body gives them the allure of a magical formula, after which nothing is the same. The nature of „change happening“ is something very much presented in ALKALOID’s music, lyrics and visual identity. Let it be one big permanent morphing!
