Besides the fact that they are weird, some of the chords are pretty jazz like too! Like bm7b5. And then there are some slash chords like F/E and Dm/c but those are an Fmaj7 with an E in the bass and an Dm7 with a C in the bass. Also after the bm7b5 comes an bm7b5/A whim is effectively the same chord but a different inversions. It can be played just using powerchords but there’s a guitar doing arpeggiated chords so for the harmony it is kind of Imoorland to actually know the underlying chords
