From 1998 to 2011, the trio was resting while the band members traveled all over the world, each with their own very different projects.
In 2012 ACO did celebrate their 20 years anniversary in the current constellation, which is the American violinist, Ruhie Dornfeld, the Finnish jaws harp, flute and bass player, Tapani Varis, and Morten Alfred on guitar and vocals.
The trio started out performing their own blend of traditional and newly composed music, but are now concentrating entirely on their own compositions.
ACO released their fourth album, this one with all new music, in 2012, followed by touring in Denmark, Germany and Finland. The trio performed at Haapavesi Folk Festival in Finland in the summer 2014.
