Early life

Career
K-391 began his career as an artist in 2009, then known as Keosni. Later he changed it to KON-391, an acronym of his full name accompanied the figures "391" meaning "CIA" by the order of each letter of the alphabet. Then he finally shortened it to K-391.

In 2017, K-391 and Alan Walker released their collaborative single "Ignite" which is a reboot of his 2015 track "Godzilla" which featured vocalist Marvin Divine.

The song, which was originally released as an instrumental, was released on 7 April 2017, through Walker's record label MER as well as Sony Music. A version of the song, featuring vocals by Norwegian singer-songwriter Julie Bergan and South Korean singer Seungri was later released on 11 May 2018. Although the instrumental was released through Mer Musikk and Sony Music, the vocal interpretation was released under Liquid State, a record label that focuses on electronic dance music. The vocal interpretation was praised as being significantly better than the instrumental and it was a huge success for K-391. K-391 went on to further collaborate with Alan Walker, remixing such songs as "Tired" and "All Falls Down".
