Can't wait to see the setlist.
It will most likely be 50-60% Road Salt songs, but the interesting part to me is what old stuff they are planning on performing. Don't get me wrong now, but Ashes, Undertow and Chain Sling have become a bit "dull" in the sense that they are often there, and it's not that they aren't great tunes, but it removes the spots for 3 other songs.
I saw Ashes when I saw them open for Opeth, and honestly I enjoy the 12:5 version more, the "regular" version is probably one of my least favorite "popular" PoS-songs. Undertow and Chain Sling are cool, but I would much rather see King of Loss or Her Voices for example. Foreword, Nightmist, Handful of Nothing and A Trace of Blood are some others I would love.
From BE they can play pretty much what they want, the album is just a masterpiece, and while I was lucky to get Diffidentia the last time I saw them, I would take it again because it's THAT good.
