Lollapalooza does it
Pitchfork does it (mostly; they offer like 25% of the lineup before tickets go on sale)
Austin City Limits does it
In fairness, prices tend to be significantly lower at this stage (in the case of Lollapalooza's early birds, they're slashed by as much as 2/3rds), so yeah, it's arrogant, but you get something out of it.
