not actually a festival at all, it's a conference for the music industry, with bands playing mostly to industry people. You have to register to attend which for a music pass is $475. Then you pretty much have to sort out a hotel out there too. So probably looking at quite a bit upwards of £600.

which will be around £400 + hotel cheapest would be around £100 for a week in somewhere potentially awful and a fair distance away + if nec, travel from hotel to gigs depending on distance and food etc etc

you're could quite easily be looking at £1000+ but if you treat it as a full blown US holiday just with a shit hot music event happening whilst you are there I guess the price ain't too bad
