Triangulum Amsterdam Triangulum, a progressive metal band with a musical palette consisting of great symphonies with heavy guitars, interspersed with subtile dynamics from all kinds of music genres for a accessible, renewing sound. In July 2017 Triangulum released their debut EP called ‘Tree of Life’. The EP takes you into a poetic story of life and death, focussed on self development. Triangulum’s musical compass is clear: accessible progressive metal, music with a meaning. The band from Amsterdam is formed by Wieger de Vries (vocals and guitars), Jelle Wester (keys), Maarten Grimm (bass) and Patrick Post(drums).
