In some ways, CMJ Music Marathon is similar to the athletic competition that it shares a name with. Five days of non-stop music requires endurance—a good set of earplugs helps, too. There are a plethora of day parties, industry panels and nighttime showcases crammed into these five days. It’s utterly impossible to experience everything that you want and equally as difficult not to wear yourself down with days that can span from 12 p.m. to as late as 4 or 5 in the morning.
