If you're going to Germany to immerse yourself in big-city excitement—churning dance clubs, matterful contemporary art, visitors and food from around the world, and street life that goes on all night—you'll probably find it in Berlin. Though rents have been climbing and there's no shortage of dirty sidewalks and petty crime, the German capital remains one of the most youthful and vibrant cities in Europe, an art and culture center with large expatriate communities and endless things to do. For urban thrills on a smaller scale, you can make a case for Cologne and even Leipzig.

Just maybe don't go to Munich. As soon as you leave the airport, you know you've reached the epicenter of German burgherdom—a place where manicured lawns, public safety, tidy storefronts, and respectful revelers in Tyrolean costumes are the norm.

In Part 1 of this interview, which announced that famed mastering engineer Bob Ludwig was retiring, Ludwig discussed his early days as a music-loving student, as a trumpet player, his graduation from Eastman College with a Master's degree in music performance, and how working with legendary engineer and producer Phil Ramone at A&R Studio awakened his interest in how records are made. In this second part, Ludwig talks about how he moved to Sterling Sound, then to Masterdisk, and finally how and why he set up his own studio, Gateway Mastering Studios in Portland, Maine.
