"Blood Diamond" Words and Music by: Eric Olson. Genre: Acoustic Folk Singer/Songwriter. Background: I wrote this song In the Spring of 2009. I had this overwhelming anxiety that my life was going to fall apart come Autumn. Not sure why or how but this song came out of me during that anxious time in my life. Also, I was listening to a lot of Nick Drake at the time and was obsessed with the "drop D" sound on an acoustic guitar. Throughout most of the song I drone between the low 6-D and string 4-D.
