Blue Devils hornline 2014 Space Chords warmup at DCI semi-finals, Indianapolis, IN, August 8, 2014. Stay tuned for Blue Devils 2015 DCI Finals warmup! Not a binaural recording, but hard not to capture somewhat of a 3D stereo sound, being surrounded by brass players! No ASMR here, but chills are likely.
