had four beds. Opeth stayed there for around two weeks and then later rented out Dark Tranquillity member Mikael Stanne's flat. After recording the basic drums, rhythms, bass and acoustic guitars, Wilson arrived to produce the clean vocals and add some guitar leads. Åkerfeldt wrote that Wilson had an "immense impact on the recording" and after working with him the group entered "a new phase". Åkerfeldt described the recording of the album as "rather smooth". Soilwork was recording in the studio at the same time as Opeth. Åkerfeldt wrote that Opeth felt like "a bunch of amateurs in comparison. They were working all the time. When they came into the kitchen for a break, we're still there, on the same break we took 3 hours ago. We don't want this to become a 'job', or something you do because you have to. We wanna have a good time, and thus we only work when it feels right." Release Blackwater Park was originally released on March 12, 2001, in Europe and a day later in North America. This was the first Opeth album to be released in North America at the same time as it was in the rest of the world. It has been released on compact disc and vinyl record formats. A special edition of Blackwater Park was issued in 2002 with a bonus second disc that included "Still Day Beneath the Sun" and "Patterns in the Ivy II". Those two bonus tracks were released together as a vinyl-only 7-inch EP by Robotic Empire Records in February 2003. The limited edition EP sold out in less than 24 hours and continues to be one of Opeth's most sought-after releases to date. Two singles were also released to promote Blackwater Park. A shortened radio edit version of "The Drapery Falls" was released as a promo single. The bonus track "Still Day Beneath the Sun" was later released as a vinyl only single. Blackwater Park did not chart in the United States or United Kingdom. As of May 2008, Blackwater Park has sold over 93,000 copies in the United States. On March 29, 2010, Opeth re-released a Legacy Edition of Blackwater Park which included a live version of "The Leper Affinity" and then a second DVD which is the entire album in 5.0 Surround Sound and a making of documentary. This version was released in North America in April 2012 by
