Branches is a band from Los Angeles that produces absolutely fantastic covers. I’ve been listening to them on Spotify for awhile, but recently found there YouTube channel, which is also fantastic. The YouTube Channel consists of covers of songs such as Seven Nation Army, Halo, The Sound of Silence, and more. I would compare there sound to The Lumineers or The Head and The Heart.
Somebody to Love (Jefferson Airplane cover)
Skinny Love (Bon Iver Cover)
