I have a rather nice one, which still goes around in the EBM scene.
In 1993 i was booker for a small venue in the Netherlands, and when i red one day the Edge of U2 fame was into Insekt i thought it might be a good idea to book them for a fun night. So it happened, and we set it up. Insekt came, we had Image Transmission open for them, and unlucky attendence was pretty bad, but hey, i had fun. Image Transmission put up a good show, and then Insekt came along, and that was rather spectacular. And the sound was HARD, and filled with BASS. It was so hard that tiles which were on a outside wall all fell off, and that was a mess. After the show i showed Erik what they had done, and he was pretty amazed by it.
They still go on telling everywhere they made a wall break down when they played the NL in 93. :D
