Recently, I listened to Porcupine's self-titled CD, which I hadn't heard in a while. As I listened, I thought, "There's a pleasant consistency to these tracks--appealing smooth jazz with easy-to-digest keyboard parts, sunny saxophone, and a good undercurrent of bass. I wonder why I've never heard this group's music on the radio."
I knew the answer, though. When your music is consistent but consumed largely as background accompaniment, it's easy for it to get lost in the shuffle of similar-sounding artists.
Such is the challenge smooth jazz and new age artists face.
