Considered one of the top music festivals in the world, Primavera launched in 2001 as a sort of experimental event for performing rock and pop bands. (Among those who’ve graced the stages since then are major acts like The Pixies, Arcade Fire, Neil Young, and Cat Power.) The annual three-day event draws close to 180,000 people to its venue in the Forum area. Despite the crowds, the size of the space means you’ll never feel cramped here. The 2015 festival runs May 28-30.
