I'm analyzing this song and I have some doubts:
I think the song is in the key of C, but he never plays a C. The chords are:
Dmin7-Bmin7b5-E7-Emin7-Amin7-C#dim = II-VII-?-III-VI-?
and later is the same but playing a A#maj7 instead of E7
I don't understand why E7 and A#maj7 works in this progression if they are not in that key. Can you always change the minor III for a dominant III?
Edit: I'm thinking that the song could also be in the key of A minor, which is the relative minor to C, so the question remains the same :)
