That's a sampling.
The price may seem high, but for an independent release, to support an artist I've admired for years, whose output - though varied is never bad - I just (personally) felt this was an easy leap to make and a perfectly fair investment... it's more expensive than a mainstream, major label CD - but it's not much different than any other purchase from an indie label or band.
My 2c anyways.
