The most famous image of Abbey Road is of course the crosswalk right outside the studio. If it weren’t for the tourists crowding the crosswalk and the Beatles-related graffiti covering its outer gate, one might pass and never notice it. The studio itself doesn’t stand out particularly from the rest of the buildings around it, and it sits in a fairly quiet posh northwestern London suburb. Here are some of the world’s greatest studios. As I stood outside Abbey Road Studios and watched a 16-year-old Colombian girl weep at the site where the likes of “Golden Slumbers,” “A Day in the Life,” and “All You Need Is Love” were recorded, I realized that a musical tour of the world - a tour of the songs that moved you to tears, or helped you through a hard time, or amped you up for a big moment - would actually be a tour of the studios, these often nondescript buildings that are typically hidden in plain sight in our cities. Modern music fans usually don’t listen to music live, unlike our ancestors, who listened to live music exclusively.
