No artist want to be classified, but if I had too, I would say “Folk Rock”.
Exene Cervenka and John Doe veered into what could somewhat be described as folk rock with their alt group “The Knitters,” but the below video was in heavy rotation in the very early days of MTV and clearly qualifies as punk, maybe tinged with rockabilly, but punk. Sound and video quality is not the greatest, it appears to be a video recording of the video on television.
X - “Hungry Wolf”
Folk Rock was the early ‘60s.
