band, something that Åkerfeldt had been wanting to do for some time. The first two songs Åkerfeldt wrote for Heritage were in the style of Watershed. After hearing the songs for the first time, Martín Méndez told Åkerfeldt that he would be disappointed if the album continued in that direction. Relieved that Méndez was not interested in doing another conventional Opeth album, Åkerfeldt scrapped the two songs and started the writing process over in a different style. In the press release for Heritage, Mikael Åkerfeldt revealed that he felt as though he had been building to write the album since he was 19 years old. In a review for Allmusic, Thom Jurek called Heritage the band's most adventurous album, describing the songs as "drenched in instrumental interludes, knotty key and chord changes, shifting time signatures, clean vocals, and a keyboard-heavy instrumentation that includes Mellotrons, Rhodes pianos, and Hammond organs". Opeth supported Heritage with a tour that would last for over 200 tour dates. The tour was the band's first with new keyboardist, Joakim Svalberg, who played on the opening track of the album. During the tour, Opeth played with bands such as Katatonia, Pain of Salvation, Mastodon, Ghost and Anathema all over the world in countries such as the United States, Europe, Turkey, India, Japan, Greece, Israel, Latin America and Sweden. The tour concluded with "Melloboat 2013". Pale Communion (2014–2015) On 26 August 2014, Opeth released its eleventh studio album, titled Pale Communion. Åkerfeldt began working on new material as far back as August 2012. In January 2014 he stated, "We've been looking at [tracking the next album at] Rockfield Studios in Wales where Queen recorded "Bohemian Rhapsody", but we haven't made a decision yet, but it will be an expensive album. There's a lot going on, lots of string arrangements that we haven't had in the past." Despite fearing that the band's new musical direction would split Opeth's fanbase, when asked if it will it be heavier or softer than Heritage, Åkerfeldt said, "Maybe a little bit heavier, not death metal heavy, but hard rock/heavy metal heavy. There's also lots of progressive elements and acoustic guitars, but also more sinister-sounding riffs." Åkerfeldt also produced the new album which will include string instrumentation, something that he became interested in doing when working on Storm Corrosion. The band members in Opeth felt rejuvenated after creating Heritage which resulted in closer relationships
