This is right out of the movie "Red State." John Goodman is in the movie and it totally sucks. Anti conservative - anti faith movie.
They have these exact same sounds in the movie and John Goodman makes fun of some religious people for thinking it was trumpets from heaven.
Red State
release date Sept 23 2011
The shoot-out is then suddenly interrupted when a mysterious loud trumpet blast echos across the sky. The remaining Coopers lower their weapons and run outside rejoicing, claiming that "the Rapture" has come upon them as the trumpet continues to play. Abin Cooper calmly approaches a stunned ATF team and confidently taunts them that God's wrath is upon the Earth. He raises his arms and stands in the face of a confused and worried Keenan in a moment of triumph, daring him to defy God as the trumpet blares.
Several days later, during a briefing before high-ranking government officials, Keenan reports that he then head-butted Cooper and took the rest of the congregation into custody. He explains that the trumpet noises were not in fact the Rapture but came from a group of marijuana farmers who lived down the road and were irritated with Cooper. As a prank they rigged up an old fire truck siren to an iPod with loud trumpet noises, unaware of the shootout taking place over the hill. Keenan is promoted despite disobeying a direct order from his superiors at the time to kill everyone at the compound. Keenan is surprised that he is not punished for his insubordinate actions but his superiors explained that their initial decision to kill the members of the congregation was mostly personal anyway and that they are satisfied with the alternative punishment of taking away the prisoners constitutional rights to due process, locking them up without ever letting them go to trial. They also laugh at the irony that Abin, who views homosexuality as an abomination, will more than likely be raped numerous times by his fellow male inmates. Keenan laments this outcome in a story he shares about a couple of hungry brawling dogs he once knew that taught him about the darker side of human nature and the way simple beliefs can turn humans into bloodthirsty animals.
Abin Cooper is finally seen pacing around his cell singing to himself until he hears "Shut the **** up!" being yelled by another prisoner (voiced by director Kevin Smith).
Original Ending
During various interactive Q&As for the film, Smith has stated that the original ending actually continued through with the trumpets signaling the Rapture. After Cooper tells Keenan to shoot him, Cooper's chest explodes, followed by the remaining family members' chests exploding one by one, and then the remaining agents' chests exploding one by one. During these deaths, the ground shakes and splits, and Keenan curls up on the ground and closes his eyes. When he opens his eyes he sees the last agent killed with a giant sword coming out of his chest, which is being wielded by an enormous armored angel. The angel looks at Keenan, puts a finger to his lips, and says "shhhhh". The angel then flies off into the sky, and as the angel banks out of the picture the Four Horsemen of the Apocalypse descend.[10]
