As many of you may know, I attended the Michael Wagener Recording Workshop back in Janauary of 2006 and I considered it be one of the greatest learning experiences in my life. I've written extensive articles on my trip. There is no substitute for working side by side with a producer who has his name on over 60 million records in an environment where you, the engineer / student, is more of a priority than the actual recording of the song. (In other words, in a standard recording situation the assistant is scum and you can not stop to ask question all the time.)
I'd highly urge anyone with the time, budget, and inclination to seriously consider attending the Workshop. You'll learn more about recording in 8 days than you had previously known your entire life. I couldn't recommend it any higher. I just wish I could afford to go everytime.
