Strom Corrosion

information taken from wiki 

Storm Corrosion is a musical collaboration between Mikael Åkerfeldt of Swedish progressive metal band Opeth and Steven Wilson, an English solo artist and frontman 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 first studio album on May 8, 2012 through Roadrunner Records.

A critical success, Storm Corrosion marks a paradigm shift for Åkerfeldt and Wilson. Not wanting the project to be a progressive metal supergroup, the two used it as an opportunity to explore their more esoteric tastes in music, including Comus and Scott Walker. Currently, there are no plans for a tour in support of the self-titled album or a follow-up.

Formation

Mikael Åkerfeldt became aware of Steven Wilson in the mid-1990s after Åkerfeldt's best friend Jonas Renkse played him the Porcupine Tree album The Sky Moves Sideways.^[1][2] Åkerfeldt instantly fell in love with the band, calling the experience "an awakening". He came to idolize Wilson, but was hesitant to contact him. Years later, Åkerfeldt received a surprise e-mail from Wilson who had been given a copy of the Opeth album Still Life by a French journalist.^[3][4] Wilson, a fan of extreme metal, played the album during a soundcheck and was blown away, calling it "amazing". The two ended up meeting for dinner in London where Åkerfeldt asked Wilson to produce the next Opeth album.^[5] It was also during this dinner that the two first spoke of a possible collaboration.

After their meeting in London, Åkerfeldt and Wilson began a longstanding musical partnership. Wilson went on to produce three Opeth albums – Blackwater Park, Deliverance, and Damnation – and mixed one Opeth album, Heritage. In 2005, Åkerfeldt contributed some guitar and vocals to Deadwing, Porcupine Tree's eighth album. Porcupine Tree and Opeth also co-headlined a North American tour together in the summer of 2003.^[6] Although the collaboration was announced as early as 2006,^[7] it was only in March 2010 that the two began writing music together, done on an on and off basis.^[8] Originally, ex-Dream Theater drummerMike Portnoy was to be involved, but was excluded because Åkerfeldt and Wilson felt the music would have little room for drums.^[8] In early 2011, Storm Corrosion was announced as the project's title.^[9]
