Rodney Howard-Browne is on one of the tapes. To learn more about him, listen to Hanegraff's Counterfeit Revival where he (RHB) instructs people not to pray but just received the experience that they were receiving.
To these tapes, aside from the one with RHB I remain open minded- particularly the one with China and the Kansas one. I won't say that they are real, but I won't say they aren't either. Beautiful sounds. The one in Maryland sounds like the Choir sound though on the Kurzweil piano.
I don't know if they're real either but that last one gave me the heebie jeebies.
