Storm Corrosion

Storm Corrosion is a musical collaboration between Swedish musician Mikael Åkerfeldt of progressive metal band Opeth and English musician Steven Wilson of the progressive rock band Porcupine Tree. Åkerfeldt and Wilson began a longstanding musical partnership in 2001 when Wilson produced Opeth's fifth studio album Blackwater Park. The two began writing together for a new project in 2010, releasing their self-titled debut studio album in 2012 through Roadrunner Records.

A critical success, Storm Corrosion was a musical shift for Åkerfeldt and Wilson. Not wanting the project to be a progressive metal supergroup, the two used it as an opportunity to explore progressive folk, including influences from Comus and Scott Walker. No touring to promote the album was undertaken, nor were any plans for future music established at that time, with the two instead opting to return to their respective other musical projects. However on May 31, 2026, Wilson posted the following on Instagram: "Storm Corrosion 2, Stockholm, May 2026."
