I love how two major chords back and forth can sound so dark. In a class at Webster, a very talented composer and fellow student was commissioned by the teacher to write a song that sounded minor but without using minor chords (which is always up for interpretation btw), and this E – C progression would’ve been perfect.
Chords open in a new window if you want to play along, here
Chris Cornell at his best here circa ‘96.
