I just attended the Nashville session... I thought it was pretty great. I too felt slightly misled, or rather disappointed that Frank wasn't there - but I got to meet him before and see him speak/teach before. Mark was awesome! What I thought was great about this course is that it teaches many PRACTICAL things. Problems we face in mixing/recording, and what to do about it. And many tips and tricks to make the mix sound better... Stuff you only get when you listen to someone who's been doing it for decades. We all know how to push faders and turn knobs but courses like this explain the WHY. I got a lot out of it actually. I also felt I knew a great deal going in and I'm sure many attendees of the course do as well. But having someone like Mark demonstrate practical things was gratifying when I learned I was doing things correctly - and inspiring when I learned a new trick or see how to do something better. I've taken the full range of Pro Tools training and have years of experience mixing, but what I've always really wanted was to mentor under someone who knows these practical things. This class does that by cramming a lot of stuff in 11 hours. I wish it was two days!
