SOUS-GENRE - Le Punk-Hardcore 1980

How I would go about composing a punk-hardcore song like the bands of the early 80s (Minor Threat, Bad Brains, S.S. Decontrol, Black Flag, Dead Kennedys...). The song starts at 8:29. (My E string went slightly out of tune during the explanation between 5:54 and 6:30. I apologize for that.) This is a new video concept (somewhat inspired by PV Nova's "musical experiments"). The idea is that in each video, I try to compose a song in a given subgenre of punk-rock.
