How cool would it be if the band did an audio broadcast of their shows as part of the U2.com subscription? Surely their is a way to stream their IEM feed to us without the count ins.
Not a pro myself but if I had to guess it might just be that they really haven’t had the time to reherse it enough to feel comfortable. Read either or elsewhere that something similar has been happening during Acrobat and that’s been played every night of the tour so far.
