Acts like Alana Grace or Miguel from past lineups had to either be paying for their spots or were strung along as a package deal with an act Coachella really wanted. I just can't see another way that GV would book them.
During the early days of rock n roll on radio the term "Payola" was coined & pegged to the small scandal of record companies paying DJ's for spins. Today of course its standard procedure.
If you wanna come up then I suggest gigging hard. Any aspiring act is never going to make it without touring relentlessly especially a punk band. Not too many shortcuts in the music industry unless your born into rock royalty or a label is 110% certain that you will be a great ROI.
