"Here you can see the musicians doing their thing, fully mic'd-up and using headphones to A) listen to everything being picked-up by the mic's and B) to communicate between themselves and the people in the CONTROL room. This is where all the magic happens!
During a live webcast switch between LIVE room and CONTROL room to get a complete picture of what goes into a studio session.
(Audio sometimes available; dependant on the musicians and the circumstance of the studio session)"
