[1] The group was founded in 2012 by Andrejs Reinis Zitmanis and Mārtiņš Matīss Zemītis when they were both studying at the Pāvuls Jurjāns Music School in Riga.

In 2015, they won the upcoming musician competition First Record (Latvian: Pirmā plate) at the Riga State Gymnasium No.1.

Their subsequent creative efforts culminated in the band's debut album, which was preceded by the singles "Priekšpilsētas valsis", "Laikmets" and "Šajā sētas pusē", which were immediately given play time by Latvian radio stations.

On September 22, 2017, Sudden Lights presented their debut album Priekšpilsētas (Suburbs), which was composed of 10 songs in both Latvian and English.

The band's first self-organized concert, in which they performed songs from the album, took place at the Daile Music House in Riga on April 12, 2018.

They performed in Valmiera, Liepāja, and Alūksne before the COVID-19 pandemic forced them to cancel the closing concert scheduled for March 20 in Riga.

Outside of writing the album, on which the band collaborated with the singer Annna remotely via Zoom, the song and radio single "Aizņem man vietu" was recorded.

In the autumn of 2022, the band worked on its plan for a tour of Latvia, attracting the rapper ZEĻĢIS as a special concert guest.
