[3] Yli-Salomäki forms the electro-pop duo Ouden with baroque singer and performance artist Debi Wongl and he is founding member of hardcore punk band Puhelinkoppi.
Later he studied composition and orchestration with Harri Vuori [fi] at the University of Helsinki in 1998–1999 and privately in 2000–2002.
Yli-Salomäki has worked as a radio journalist in Yleisradio, particularly focusing on contemporary classical music in programs like Aikamme suomalaista musiikkia (2012–)[2] and "Uudet levyt" (2018–).
Especially in the 2010s, his music was often slow, calm and focused, as evidenced by the titles of many works, for instance the "Lingering" series for solo various instruments.
[8][9][10] Stylistically Yli-Salomäki's work draws on, for example, post-minimalism, colorism, neo-mysticism and slow music thinking.
