I'm guessing it's difficult to convince a major label to release your first record with them on a medium that has such a niche market.
How niche is it for gaslight? I wouldn't be at all surprised if > 5% of Gaslight album sales are vinyl. Sure its small, but its large enough that it should at least get some focus. How hard would it be to have an option of the super bundle that costs 70 and includes the record?
