In the spring of 1992 Irfan van Ewijk, Duncan Stutterheim & Theo Lelie had the idea to organize a big rave for schoolgraduates. The rave had to make an impact in Holland and was based on the by then popular rave-formulas in England. With the title 'The Final Exam' the rave took place on 20th of June 1992 in the Jaarbeurs in Utrecht. 12.500 people came to the rave, for Dutch standards absolutely unique! For some years now, The Final Exam rave has been a reference for other big raves. ID&T made name and fame in the Dutch music-scene. After the rave in June 1992 Theo Lelie left the organisation. At the end of 1992 the ID&T's first Thunderdome CD was released. In 1993 this succes-formula was boosted by the co-operation with ARCADE. More than 1.000.000 albums have been sold. ID&T's trademark, the mysterious wizard, can frequently be found on ID&T's merchandise articles such as t-shirts, longsleeves and e.g. caps. Besides the partnership with Arcade ID&T produces albums, video- and vinyl-recordings independently, or in partnership with other labels. In the autumn of 1994 Irfan van Ewijk agreed with Duncan Stutterheim to leave ID&T.
