About IO Festival
Welcome to the 33rd edition of the biggest annual student festival of the Netherlands… IO Festival! During this 9 hour music festival, which will take place at the TU Delft faculty of Industrial Design Engineering, 1600 students and employees will come and enjoy a wide variety of bands, DJs and other performances on three different stages.

After the very successful IO Festival editions of 2012 (Industries Ignited), 2013 (Illumination) and 2014 (Utopia Disrupted), this year’s edition will turn the faculty of IO into a wonderful mechanical circus tent, where musicians, magicians and acrobats will merge together and take you on an unforgettable musical journey. On the first of May, 2015, IO festival: Cirque Mécanique, will open it's doors for the 33th edition of the most amazing music festival in Delft.
