Album review: Bon Iver's i,i is a joyfully experimental record

The early release was only part of the surprise of a joyfully experimental record, writes
.Bon Iver’s Sounds From A Safe Harbour performance at Cork Opera House in 2017 was beautiful, bonkers and deeply esoteric. Much the same could be said of his fourth album, which the artist born Justin Vernon has surprise-released several weeks ahead of schedule.
