Benoît and the Mandelbrots see the laptop as their main instrument; they are mainly dedicated to live coding. They use the programming language itself as an at first sight non-intuitive, but simultaneously expressive interface between man and machine in order to improvise sound and music. Sonic conceptions and structures are expressed live as source code, and interpreted by the computer. With the flexibility of live coding the sounds are generated specifically to fit the room characteristics and the audience of the performance.
As every performance setting is unique and improvisation is the main paradigm of the group they don’t perform ‘works’ in a classic sense, but consider their whole oeuvre and underlying concept as their work, which expands with every performance. The musical results vary from electronica and ambient to experimental, noise, drones and avant-garde depending on the event, audience, venue and course of the collective improvisation.
Since 2009 the band has played more than 90 concerts in Germany and all over Europe. They received an Honorary Mention at Prix Ars Electronica 2012 in the category Digital Musics & Sound Art. In 2016 they released their self-titled album on the Karlsruhe label Syff which is available as double vinyl or digital download.


Shelly Knotts is an improviser who performs with computers and other humans. Interests in code, data and networks have lead her down strange and diverse musical paths from electroacoustic composition, through jazz and noise music to algorave. She experiments with generative and AI techniques and opinionated algorithms to make music. She has performed at numerous Algoraves and other live coding events worldwide, solo and with collaborative projects including algo-pop duo ALGOBABEZ. In 2017 she was a winner of BBC Radiophonic Workshop and PRSF ‘The Oram Awards’ for innovation in sound and music. Previously she was an academic, researching on projects around the use of AI, data and networks in improvisation and composition.


Friedemann Dupelius, DJed with the Mandelbrots in Karlsruhe’s iuno bar in 2010, has published texts and radio features about live coding, and makes music without live coding under the name Friday Dunard.


Alo Allik is an Estonian sound artist who has performed his live coded electronic music and generative computer graphics throughout the world. His aesthetically and geographically restless lifestyle has enabled him to traverse a diverse range of musical worlds including DJ-ing electronic dance music, live electronic jam sessions, electroacoustic composition, free improvisation and audiovisual performances. He has forged collaborations with a number of curious and innovative musicians, writers and visual artists along the way focussed on exploring links between science, technology, creativity and tradition. His most recent project kurivari derives its musical style from analysis of traditional rhythm patterns fused with sonic material generated with genetic sound synthesis algorithms. This fusion is intended to create a sonic environment that explores the uncertain area between rigid rhythmic structures and completely form-free noise improvisations, the edge where order and chaos meet and create interesting moments of complexity intermittent with simplicity.


Lime68k is a laptop noise woman from Brittany. Laptop noises include bass sounds, many percussions and other unspecified noises. She also uses the laptop for visual noise and she also gets noisy about the things on her laptop. Last time she brought her laptop to a stage was for the opening act of Autechre in Rennes, and she's eager to open her laptop again on another stage.


Haelmo is a live-coding audiovisual duo formed in February 2024 in Karlsruhe, blending visuals and sound into rolling beats, Hydra feedback, and club mayhem.


pastagang is a creative group that anyone can join. They tend to hop into the same collaborative live coding environment at unplanned times. you are welcome as well by going to nudel.cc.


As grainn, sound artist and electronic musician Adrian Reichardt (“Ardt”) works with code and sound to create sonic landscapes and rhythms that fall somewhere between glitch, noise, IDM, and deconstructed club.


stroboalex is a musician and music informatician from Karlsruhe. In a freak accident he lost his ability to play the guitar and acquired a computer dependency for making music.


Pose Coding is an interactive live coding instrument that enables visitors to create sounds through their own body movements. The system records the person's body poses using a webcam. The installation analyzes the posture and assigns it to one of twelve different body poses. Each of these poses is linked to a visual symbol and a block of program code that influences the sound generation.


Jakob Schreiber explores the interplay between human intention and technological response. His interactive installations and performances explore how movement and presence can be translated into sonic and visual material.

pj schruck is a secret supporter of Algorave in Karlsruhe since 2015. He is honored to open the night, first with Käsespätzle, then with a cozy-synth-set.

10 years for this, 12 years for that :)
