In The Ancient Army (2017), artists Katri Paunu and Roos Hermsen took their puppetband a step further by collaborating with musicians Joost van Vuure (bass), Ivy van der Veer (drums), Koen Hobbelink (guitar) and Luuk van Oostrom (guitar). Six monsters: a dragon, an alien, a skeleton bird, a snake, an octupus and a dozen cockroaches creeped on a twenty minutes doom metal journey that they performed in the Vondelbunker, Amsterdam.
