Undoubtedly great recordings, but with the possible exception of "Light As A Feather", imo they don't have the historical relevance of the ones in question. When there are so many "greats" to choose from, I think that "greatest" should be reserved for those that are not only great performances, but are also very important bynbeing landmark recordings in the evolution of the music. "Headhunters" was a masterpiece of the genre and incredibly influential with funk grooves that are still being sampled today. For better or for worse, hip-hop as we know it today would be very different had there been no "Headhunters". The addition of Jaco Pastorious to Weather Report's lineup would forever change the way that the electric bass was played and its role in a rhythm section. The influence of Jaco, not to mention the band, cannot be overstated. I like the choice of "Light As A Feather" for bringing the "Spanish" flavor to fusion-jazz; something that would become very prevalent.
