I had a similar experience, playing in bands during high school. I played clarinet in the marching band and concert band, and tenor sax in the stage band. Particularly in the stage band, I got blasted in the back of my head by the brass section.
I gotta think that exposure was as high SPL as the rock bands I've played with.
P.S. IME, the Etymotic ER-20s don't color what you're hearing, beyond reducing the level.
