yeah, I listened to the clip... is this really something that astounding?
I take it you've never been involved in the world of string music People tend to go really crazy over stuff like that.

This definitely is not possible with an e-bow because the e-bow doesn't apply pressure to the string. Choking the string is what is helping make the low notes. You can also apply the same principle and play very high notes with the bow... often by mistake.
