Arnau Obiols has always been interested in traditional Pyrenean music and in learning about the most local songs and music. This musician from La Seu d’Urgell has explored jazz and improvisational drumming, specialising in reviewing the musical traditions of the Catalan-speaking regions and especially of the Pyrenees. His music brings together two different worlds of roots music and musical experimentation. This union has given rise to Tost (Microscopi, 2019), Obiols’ latest personal project—a kind of intimate sonorous ritual in which he invites us to participate.
