Springtime in the Northern Hemisphere means a host of urban and outdoor EDM festivals. Here is a list of April events: two in Austria and Switzerland, and one apiece in California (Coachella!), Colorado, Germany, Malta, the Netherlands, and Romania.
The variety of settings for these festivals is substantial: two are beach, one is snow-filled mountains (three others are nearby snow-filled mountains), one is the desert, and one is a deserted shipyard. It is not too late to mark the date for any one (or two, or three) of them.
