In no way will the top A&R's who actually have the power to sighn someone be there...think about it like this say they rent a ballroom at a hotel for say 1,000$'s and payed to advertise on the radio for 2,000$'s...Now factor in that they may charge 20.00$'s to register...the room packed all day from morning to eve. estamate atleast a 1,000 to 2,000 people to show up that is 20 to 40,000$'s! Then out of that large bunch of people they will pick say 100 people to go to Vegas where then they rent a club, make some flyers and dress it up like a night out...they will show cats a video with a big time A&R on it who will endorse the event and for the chosen few they will then charge them around 300.00$ to take part in the big showcase that's ummmm....that's another 30g's...now factor in that they probaly do this all over the country and you got ya self a sure shot SCAM.
