Joni Mitchell
Joni Mitchell's Blue album is considered one of the finest LPs front to back ever written. She's a fan of original tunings and unique, hard to follow picking patterns. Her technological temperments make her one of the most influential folk indie icons. Her favorite guitar is a 1956 Martin D-28.
Noveller
While live ambient looping is a pretty common technique today, it wasn't really a thing until Sarah Lipstate, aka Noveler, took the stage. He was handpicked to open for St. Vincent and Iggy Pop, and her vibe of ever-shifting sounds make her music hypnotic. She typically plays on a Fender Jaguar.
