Umami tunes
If you go to Tokyo, there's a good chance you'll develop a new appreciation for shopping malls. The Japanese know malls. They know just what to do with them. Inside a Tokyo mall, you can peruse the usual handbags and shoes in their unending variety. But you can also stare at Fuji apples as large as a baby's head swaddled in tissue paper, flip through the world's most exquisite stationery, stock up on fabric from the 1920s, and taste things that will haunt you well into retirement.

In defense of sticker shock
There are faster ways to start an online fight, but not many. Say “$10,000 DAC” and watch audio-forum commenters descend like pigeons on a dropped hot dog, flapping and furious. They’ll tell you the designers are crooks, the buyers are dupes, and anyone not DIY-ing with AliExpress kits is a poseur.

Doing it for themselves—and for us
Women have undeniably become the most dynamic and vital creative force in music today. Without their good energies and ideas, music, which in the digital age has become more background than art, would be much less interesting and inspiring.
