More than 1,000 bands will take over scores of New York City's rock clubs during this massive annual celebration of indie music. Also on tap: the usual assortment of seminars, parties, meet-and-greets and panels. The event is famously cutting-edge, having showcased Arcade Fire, Lady Gaga and R.E.M. before they were stars. The 2015 edition featured the Album Leaf and up-and-coming artists like Car Seat Headrest, Kero Kero Bonito and Drinks. For more information, visit cmj.com.
