I 've recorded 60 minutes of total silence, though I have no idea what went wrong. The mic was plugged in at the right place, I checked it twice (I know what nerves can lead to, and I know I still get nevous when seeing my favorite band for the 35th time ) When they came on stage I pushed the micplug again, to make sure it was still connected. What I didn't check (I was standing first row, security right in front of me) was if the levels were moving. The gig was amazing, I had a hard time not to sing along... Dissapointment was enormous when I got home and plugged in the headphones Checked the equipment later on, and it seemed to work fine... I was lucky in a way, they played another set in my country the next day, blinding set again and those recordings were perfect, but still totally different from what they did the day before ...
