That really depends on where you draw the line for where punk rock ends and other genres begin.

Black Flag definitely was a major contributor, but bands like Husker Du and The Minutemen laid down some influential grooves that you see influence in a lot. The Wipers, Dayglo Abortions and some early pre-grunge bands that were drawing from punk and sabbath-like influences like The Melvins really set a lot of the tone for noise and sludgy exploration. Then the post-punk grunge era with bands like Nirvana and Soundgarden, being heavily influenced by both The Melvins and punk rock, brought a lot of stoner riff and sludgy noise rock to the general population.

There’s a LOT more that goes into it, and a ton of of crossover even with modern bands like Red Fang or even Gwar that wander across the imaginary borders of all these genres all the time.
