Even though this is an album from Porcupine Tree frontman Steven Wilson and Opeth fronter Mikael Akerfeldt, do not expect many similarities with the two bands.
Storm Corrosion is a collaboration between the two (and including Gavin Harrison on drums), in which they go back to their inspirational roots and create haunting, beatifully simplistic pieces of music. The music is mostly guitar driven, but also includes pianos, woodwinds and orchestral arrangements.
Sometimes smooth, sometimes disturbing, as a whole it can at first seem like a challenging listen, but it is a rewarding experience.
