sorry for the late reply BUT i think i sort of got it. the dissonant yet kind of beautiful sound is not from the chords but mostly the tuning. he's kind of fashionably out of tune and there's not really a way to describe it so just eeeever so slightly tune all of your strings down until it sounds right. not quite a half step down but around there. the first chord he plays is a regular open E major, then the second chord is an open Amaj7, the third is a G#m played as a barre chord on the 4th fret, and the last one is a regular open A major. for the E major and A major, slowly strum all the strings but the first one, for Amaj7 and G#m strum all the strings. the solo part is based around the C# pentatonic minor scale which sounds complicated as crap but is pretty simple, just look up how to play it and practice it a bit. i don't know where on the fretboard he plays it but i play it at the 6th position because it's the simplest. after you got the scale down you can just figure out the solo by ear, playing notes inside that scale. same goes for the improv at the end, don't be afraid to go up to the first string cause he does!

also i'm not entirely sure about the Amaj7, it sounds more dissonant in the video. maybe it's an augmented or sus chord.

coolest person ever i know it

He’s literally Nick

I appreciate you so much
