jesus christ you people have no lovelovelovelovelovelovelove clue what you're talking about.
its standard practice internationally for opening acts (ie non-headliners) to provide their own backline, moreso LOCAL (as in local to the country, not singaporean) openers who are usually grateful enough to play the show let alone get paid. remember people are paying to see the headliners, not some two-bit opening act.
hell, its common to see on touring band riders and contracts that opening acts have to provide their own FOH mixer and mics even, not just the backline. anything otherwise is a gesture of goodwill, not the norm. of course, we're talking about proper shows here not some DIY underground gig. let's not even go into the fact that in singapore bands rock up to a show with their guitars and drumsticks with no backline, literally unheard of anywhere else in the world.
the babble about foreign bands coming here and expecting bands yadayada is pure wank. crue or anything other band couldn't care less about who,if anyone opens the show as long as it doesnt affect them. remember they DONT NEED an opener. THE OPENING ACT IS NOT GOING TO DRAW A BIGGER CROWD FOR THEM. if a single member of their crew helps the openers out they are losing money if anything. dragonforce didn't have an opener here because they would have to wake up earlier for soundcheck. fair enough!
singaporeans are being babied and people are still bitching. wake the lovelovelovelove up goddammit.
