my guitar instructor and I figured out the chords for "shelter" by
corrosion of conformity. I think for sure 100% that the chords being
strummed on steel pedal guitar by Bruce Smith are bar chords
fretting down the neck without taking your fingers off to make...

AmAm Piano Chord 
 GG Piano Chord 
 GmGm Piano Chord 
 FF Piano Chord 


your chords Em G Am C although different sounds good you could
write a different song so I almost thought there was a different
version to this song or maybe I misunderstood what was meant.

thanks for the chords anyway.
