To promote their new KIN phones, Microsoft threw a string of parties this weekend featuring the music of Passion Pit, the Black Keys, and the Ting Tings at “secret” New York locations (including an elementary-school gym). Luckily, our photographers are like Sherlock Holmes (pre–Robert Downey Jr. edition) when it comes to sniffing out rock shows, and we have images of the intimate events available for your perusal. Yay, corporate sponsorship! Elsewhere, stages were graced by Taylor Swift, Metric, Bear in Heaven, the National, Oneida, Deer Tick, and Dr. Dog.
