As a buyer,i can tell you what i'll use to help me to choose between two cd's:I'll definitely choose for the cover,if they both sound good. First of all,i don't like photos on the cover.I'm going against the tendency here,but i like to have the performers on the back and a nice artwork on the front.Not that I'm craving to see four smiling faces,you see...and photos can be pretty boring. if the artwork is original,nice,and tasteful,I 'll pick the cd,happy to score both nice music and a visually appealling object.It means to me,that the musicians come from a good melting pot.You always assume the artwork has been created from some friendly collaboration. Good ,likeable photos are difficult to find.Usually you have low-level photos coming from concert shots- all musicians look the same in those photos.With the same frowny expression and shiny face.I always go for the artistic,black and white or re-elaborated picture.Otherwise,it looks horribly home-made to me.
That's it.I must confess that the visual aspect of the package is what gets me to buy the cd...otherwise,I can spend the money going to the concert.
