Some of my friends organized a Nepathya concert in LA one week before ANA event. From what I heard, the organizers had to sign a contract with the band that stated all their demands during their stay, which is fair if you ask me given the reputation of the band. But some of the demands were outrageous. They don't want to interact with Nepali people outside a concert venue. They will only stay in a 4 star or above hotel and each band member gets their own room. After the concert my friends had to take them to Vegas to show them around. They ended up paying a fortune for their foods and individual rooms in a 5 star hotel. I could't make it to the concert but I heard it didn't go well and ended early because of some technical issue. The band was furious with the management and the organizers suffered a huge loss. I blame the organizers here because they knew who they were dealing with. The concert was announced just few weeks before the actual event and they had very less time to manage. But what @casino said is spot on!
