DANIEL ROZENHALL and STEN BACKMAN met in the early 2000s and initially worked together with record productions for the label Fylkingen Records, of which Rozenhall was a record producer and Backman made graphic design works for record covers.

Since 2014, Rozenhall and Backman have done collaborative works with Rozenhall’s music and Backman’s visuals. They have performed and shown their works at, for example, Issue Project Room in New York, 2014, the Colour out of Space festival in Brighton, 2016, and numerous times at Fylkingen, Stockholm.

In January-February 2018, Rozenhall and Backman were touring in China and Thailand together with Lars Åkerlund and Lise-Lotte Norelius as the collaborative project Lab for Life-Long Sound Dysfunctions (LLLSD).

In January-February 2019, Lab for Life-Long Sound Dysfunctions made another tour in Asia, including performances in Hong Kong, Macau, Taiwan, Okinawa (Japan) and Thailand.
