The group's repertoire covers everything from old music hall numbers to hymns. Often the songs are rooted in the provinces of Jämtland and Hälsingland where the group's members grew up. The music is quiet but emotionally charged, and arrangements are built up around Emma's singing, which is the heart of the group's sound. It is an expression of its members' yearning to make simple, intimate and acoustic music.
The group has toured throughout Sweden and also played in about fifteen different European countries. They have also appeared in Japan and several times in the Unites States and Canada.
Triakel has recorded one single CD (‘Innan Gryningen’) with Benny Andersson of ABBA, and six full-length CDs of their own.
