Jim Morrison

The former Doors singer led a pretty complicated life, and much of his fame was based on his looks. He's one of the greatest rock legends of all time, but he also never considered himself to be a good singer. Spoiler alert: he wasn't. 

Bon Iver

Bon Iver is a titan in the indie genre, and his sound is based on weird chord progressions, intense vocal filters, and puzzling lyrics. Also, despite being a band for a long time, the sound never seems to change. Lately, Bon Iver has been working on writing and production with other artists like Taylor Swift.
