Another day, another free download. This time the former festival trap maven Carnage has released “Mara.” There’s not huge story behind this one, no wild reason why he’s giving bits away; he just wanted to release something to say “thanks,” which is usually reason enough. What is “Mara,” you ask? Oh, nothing but a massive elector house number. If you’re not into the “Animals” era of EDM right now, you will probably want to steer clear, but we imagine many of you will be going all kinds of bananahammer when this one drops in the club/rave/festival. You already know.
