In the past few years I have been able to acquire tape recordings of what appears to be angels singing, at four different locations, one in China and three in the U.S. The tapes were buried in storage boxes until recently, when I decided to search for them and make them available on my Web site.
Someone has asked how do we know these are angels and not demons. Easy answer. Praising Jesus, the Son of God, is not in the job description of demons! They cannot stand to be around when praise to Him is going on, because that reminds them of their defeat on the cross.
