Born and raised in Bielefeld, Matthias Frick, who assumed his mother's maiden name "Sieren" as his musical alias, eventually relocated to Berlin whilst pursuing a masters in digital signals processing and working as a software engineer for Ableton. Since, this transition would continue to inform his music production. His soft spot for UK bass music is recognizable in a haze of reverberant vocal snippets, spherical field recordings and experimental soundscapes. Having crossed paths with Ki co-founder Christian Löffler while playing at a festival some years ago, Löffler was convinced that Sieren's music would sound as good on the radio or home stereo as it does on the dancefloor. This fateful union paved the way for their first collaboration which saw Sieren remix Christian Löffler's "Notes" on Ki Records in 2014.[info from label]
