INNER VITRIOL is a progressive-dark metal band based in Bologna (IT).
The band - under the former monicker “Vitriol” - released two albums with the American label Melodic Revolution Records. Their full lenght Into The Silence I Sink was highly acclaimed by the international press at its release and the American radio show “Prog Metal Show” put it at the 8th place in the "Top 50 progressive metal albums of the year". INNER VITRIOL have toured extensively across Italy, the UK, Poland, Austria, Germany, Belgium, the Netherlands, Serbia, Bosnia, Hungary, and Russia, sharing the stage with Dream Theater, Sons of Apollo, Pain of Salvation, Evergrey, Soen, Kingcrow, Votum, Riverside, and Geoff Tate.
The monicker stems from the acronym of one of the most famous mottos of Renaissance alchemy “V.i.t.r.i.o.l. - Visita Interiora Terrae Rectificando Invenies Occultum Lapidem” (Enter the bowels of the Earth and, through your purification, you will find the hidden stone). It is a metaphor representing the path of man inside his own Ego in order to finally find the philosophical Truth. The duality of the locution “inner vitriol”, referring both to a corrosive chemical compound and to the renaissance motto, well describes the essence of the band, constantly pursuing balance between aggressiveness and introspection.
In 2023, INNER VITRIOL released a live DVD and two singles with accompanying music videos, Endless Spiral and Impressioni di Settembre, a reinterpretation of the 1971 Premiata Forneria Marconi classic. In 2024, the band toured the EU and UK with Evergrey and supported Geoff Tate on his Italian tour dates.
In early 2025, INNER VITRIOL released the EP Butterflies, featuring the eponymous single, and toured Europe once again with Geoff Tate. The band is now preparing to release a new full-length album, Semper Tacui, scheduled for release on March 20, 2026. The album will be promoted through two singles accompanied by official music videos, Waterfall and Weaker and Fading, as well as headline shows across Italy and a European tour planned for spring 2026.
