I've heard his songs on the radio for 20 years, but never bought an album until this one.  There are many "guest" appearances by other artists, so each song is very different, reflecting that artist's talent combined with Santana's guitar work.  Mellow yet rocking at the same time.  Long tracks, great to listen to in the car, very satisfying.  I'll probably check out earlier Santana releases now that I've gotten my feet wet with this one.
