I fail to see the connection to live skull as well.

0:37-0:50 on Sparky is almost exactly the same hook played more abrasively + every riff mentioned uses chromatics in the same way for a slight feel of menace

No it's not. Please stop trolling me johnny, it's cruel. Live Skull play Glenn Branca and SY derived no wave music.

I'd say it's most reminiscent of Fugazis guitars (but not plagiarism), Fugazi was influenced by those same two artists so mb that's why they sound similar to you.

Then why is their 3-note chromatic riff the same as June of 44's 3-note chromatic riff HUH

It's not : (

I'm phoning Steve Albini.

did anyonee realise these guys had a new record last year? seems it went almost entirely unnoticed

yes
