Formation and early period Hedberg and Ringström (both born in 1976) first met in 1991 when they were 15 years old, after the former was transferred to the same class as Ringström. They became friends, and shared similar tastes in music, films, and video games. They started collaborating on the
music tracker sequencer software
Protracker and later, the
Amiga computer system. In 1994, they started to work with PCs and formed a music tracker trio with fellow Swedish musician and producer Mikael Lindqvist called Bassment Studios. In the following year, they moved once more to
MIDI-oriented music and formed Notch, a group focusing on
acid,
techno, and
house music. Their first track was a remix of "What Would You Think" by
synthpop group Mourning After. Lindqvist soon parted ways and Notch discontinued, but encouraged Hedberg and Ringström to continue recording their own music. The pair had started to fully explore
ambient music after Hedberg's sister had picked up
Orgship (1994) by Solar Quest, which quickly became a favourite of theirs and influenced the two to make similar music. The band had built a following as Notch on
MP3.com and
Last.fm, but accumulated a bigger one as Carbon Based Lifeforms which led to increased exposure from radio airplay. When Last.fm switched from
Winamp to another media player, the band saw a boost in traffic which also increased their income. After about ten years with Ultimae, the band departed from the label to focus on digital releases and to achieve greater control over their music. In 2015, the band remastered their first three studio albums with the aim of getting "a more coherent sound between them", and for bringing out more details in the music. The album marked the band's first official music video release, for the track "Accede". It developed further during lockdowns amidst the
COVID-19 pandemic, during which both members started producing tracks separately. They agreed to explore
drone music and developed tracks by exchanging files online and adding to what the other member had put down. The book was published under this title in early 2023. A second edition, featuring minor corrections and a revised cover, was released later that year. Vadestrid also has his own solo project SYNC24. ==Band members==
