Howard . (and others)
The balancer on last nights show comes from a TV background. I won't name him.
If they had let Group 2 (Radio....The guys that do Maida Vale sessions, All festivals, and all my old colleagues!) loose on that show, the sound would have been a hundred times better!

Will mentioned the St Lukes gigs...Sounded great...why? Group 2 Studio Managers.

In the TV world, Sound balancing comes a poor 4th in the pecking order.
At any major gig....(The Proms, Glasto, etc...) The sound is provided by Radio Studio Managers. Not being bothered with pictures, we do the mix, and just provide the tele boys with a stereo feed.
Sadly, The budget on last nights show obviously didn't run to it.

I would have loved to have seen/heard what Mike Walters would have made of it!

Hope that helps!
