Great new mixing tutorial on Groove3 with Bob Horn and Erik Reichers

This seems to be episode 1 of a new series. They take a viewer's mix, critique it, and redo it themselves explaining how they're doing everything differently and A/B'ing between their mix and the viewers throughout. It's a really great format and they are excellent at getting their ideas across. Seems to be dominated by Bob Horn with Reichers making observations on the side. I can listen to Bob Horn talk about mixing all day - you might not agree with his mixing style (big effect chains, like Dave Pensado) but he really does explain things brilliantly. Excellent course to watch if you subscribe to Groove3.

I would guess it's just another way of saying the master bus. Because it always has two channels. 
 
Yeah they really improve Goldberg's mix a lot. And it was pretty decent in the first place. Just goes to show what kind of magic sauce a pro is capable of. 

Thanks guys, makes sense.
