First off, my fiance is in the entertainment business as a touring sound engineer. So I see both sides of this ordeal. First of all the crew, artist themselves, dancers if the artist is using any, and touring bills need to be paid. While yes all of that adds up, some bands out there are over-crewed, and spend way too much money on the production of a show, some of these too massive and could be easily toned down to something more reasonable. Some of these artists are overpaid for what their live show actually consists of, I.E a massive production with a mediocre show, and or a show that is being phoned in (lipsynced; my fiance wont mix shows that are not 100% live, a 3 year old kid can run audio for a show thats lipsynched). And there are also instances of the crew being overpaid, some crew guys can walk away from a year of touring with $250,000, although they are not paid when they are not on the road. My fiance works for lesser bands, although known ones from the classic rock genre.
From the fans point of view... Many artists spend too much money on the production of their live shows, and when they do this, we as the fans suffer because ticket prices have to be set accordingly to off set the bills that a tour demands (I.E Staging, Busses, Plane Tickets, Hotels, Lighting, Audio, Video, Trucking, Crew Payroll which includes per diem, Private Jets, Security which all gets paid by the week by off chance a tour would get cancelled) some of those expenses are in the million and beyond category. I also do realize that this is the way artists make money these days, but at the same time a lot of them do over-spend and are not very good at saving their money but that is a fault of their own. What a lot of these artists don't realize is that more than 90% of their fans are lower to middle class citizens and are not doing a superior job at gearing ticket prices towards these people which is why you dont hear of many artists selling out venues. These days its not possible to sell out an arena, none the less a stadium, and some artists ticket prices are so pricey that they cant even sell out theaters. A lot of artists are just plain greedy and want top dollar, but if they keep doing that less and less people will buy tickets and before they know it they are playing to half empty arenas.
Since I do see both sides of this the artists need to make a compromise and go out with a smaller production, which will in return reduce ticket prices and make shows fan friendly again. Until artists drop their ticket prices so they are reasonable, I refuse to buy tickets to see anyone.
