The Arnau Gallery project from Barcelona featured Aches within the lineup of artists scheduled for 2019, so during the summer the wall of the Arnau theater presented an intervention in which the personality of the Irish writer blends in with the characteristic forms of Musa’s graffiti. While once here, Aches also made a piece the cubicle of the Park of the Three Chimneys. Two actions that were worth following up on in video format so that we could learn about the amazing technique of Aches. This document, filmed and edited by David B. Rock is also perfect to show the laborious technical work necessary in each of the creations of this great writer from Dublin.
