Although in some recent interviews Björk has said that she doesn't want to tour much anymore, would rather focus on writing and recording/producing new music, and she's content with playing only one-off shows from time to time, there are already some concerts announced for 2017:
03-29 Mexico City, Mexico - Auditorio Nacional
04-01 Mexico City, Mexico - Ceremonia Festival
07-28 Niigata, Japan - Fuji Rock Festival
No word on musicians joining her on stage yet. The Mexican shows are coinciding with the Björk Digital exhibition there, so maybe she'll perform an acoustic, strings-only set like she did in London and Reykjavík last year. Perhaps we'll get a preview of the new material, too?
