Illegal raves represent some of the most thrilling, debauched parties in dance music history. From chaotic disused warehouse bashes to otherworldly trips into the depths of forests, partying enthusiasts have searched high and low for prime dancing locations over the years - and they never let a silly old thing like the law get in the way.
At times, these parties also represent more than just a good time. They can be defiant, political acts, that channel the raging energy of oppressed youth.
See the gallery of images below for some of our favourite illegal rave shots.
