Need help identifying a song

Does anyone know the name of the song which plays in the very first scene of Numb3rs Season 5 episode 5? It's been driving me insane, and I would really appreciate the help.

Let me google that for you:

this is what I found.

Thanks for that, but those songs are not from the opening scene. The track I am looking for is at the very beginning of the episode, and as far as I can tell, it isn't listed in any sort of episode music guide. No discernible lyrics either, just a frustratingly repetitive chanting/vocalisation, which makes lyrics search useless as well.

Sorry for double posting, but I've snipped a sample of the song and you can listen to it here: http://www.watzatsong.com/en/name-that-tune/383526.html

If anyone can help, I would really appreciate it.
