Producers and engineers are the human engines that drive and shape the sound of the recordings we know and love—as well as the ones we've yet to hear. In Part 2 of our three-part Studio Confidential interview series, Mike Mettler talks with Sylvia Massy, who has worked with Prince, Jason Isbell, Tool, and many, many others, about what elements make a hit record, what album made her want to become a producer, and why Prince was such a, shall we say, tortured genius.

If you really want to know how your favorite albums came to be, you can't go wrong talking with the men and women who are in the studio day in and day out with the artists—i.e., the producers and engineers. So we're doing exactly that. In Part 1 of our Studio Confidential interview series—there will be three parts this week, with perhaps more to follow—Mike Mettler talks with Chuck Ainlay, who has worked with Peter Frampton, Mark Knopfler (and Dire Straits), George Strait, and many, many others—about his production philosophy and who inspired him to get behind the board in the first place.
