I always preferred the instrumental pop and rock on the radio. I feel that hearing those records was more important than any one jazz album.
When I was fifteen I bought my first jazz record, the Ramsey Lewis Trio's Hang On Ramsey. That was a big step for me because I always found the liner notes of jazz albums to be intimidating. I probably would have been content to listen to that level of music had nothing else come along.
Four months later I bought my first hard core jazz album, Groove Holmes' Soul Message, on the strength of his hit single Misty. That one is still one of my very favorite albums, and it released any fear of intimidation.
