Every Indie-Folk Revival Artist

Remember in 2009 when a certain London-based band released an album and then all of a sudden folk music was everywhere for all of the 2010s? Try to guess every artist (that I can think of) from that era. Completely subjective. First column is the obvious ones, second column is more niche. Let me know who I missed. (No, Noah Kahan doesn't count, he is Indie-Folk Revival REVIVAL.)
