Do yourself a favor and listen to this Bon Iver cover by Knesset. This 3-piece Phoenix-based band covered "Holocene," and it's a truly impressive translation of what was already a beautiful original song.
Knesset adds a fully lush new wave style to a song that would've otherwise been considered indie folk. The atmospheric effects and delicate synthesizers are the perfect mix to create a still-tasteful and catchy cover without overdoing it. Knesset's melodic approach gives this track a new perspective but can easily still appeal to the same audience that Bon Iver has won over.
Knesset released their latest album, Coming of Age, last year, and I think it's one worth checking out. As for the Bon Iver cover, you can get that here.
