Topic: Stereo Mic for Hot shoe.

[momule]

I have a friend who is looking for a stereo mic for his EOS 5D Mark II.  He said he seen one somewhere that was a little stereo lavalier mic that mounted via a hot shoe.  He said they were about the size of some of the AT 835's and were mounted in a DIN bar and had a single mini input. 
But of course he couldn't find it now.  Anyone know of a good mic for this application.  It will be used for Live blues shows. 

Thanks for any help.
