The music I heard from outside is the sound of the breeze fluttering through the archways and pouring over the opening, a deep hum like someone blowing into a six-story beer bottle.
 

The acoustics are utterly alien. The slightest noise is amplified tenfold, echoed and re-echoed thousands of times until it's barely recognizable. A handclap sounds like a gunshot in the grand canyon, a drawn-out ripping sound that fades slowly. Our voices are almost impossible to understand. Each syllable of each word takes on a voice of its own, repeating and reversing and tripping over itself.
I go to the opposite end of the room from Nathan and hide behind a pillar. I softly whisper, "Hey Nathan" and hear it take flight, amplify, and swirl around the room from every direction like a swarm of hissing bats.
"Hey--"
"He--"
"Na--"
"Hey Na Hey Na Hey Na--"
"Hey hey--"
"Heynaheyna--"
"th-th-th-th"
"an-an-anheyna-an-anhey"
"--athan."
"N."
"N."
"n."

Overwhelmed...
