Now that we have thoroughly covered the 50's and 60's, it's time to move into the 70's. Miles ushered in the 70's with "Bitches Brew". I saw him live with that same group before the album came out, and fortunately I was with some guys from New York (they seem to know everything about new music) because the experience was the same as turning up a bottle of whiskey, and tasting wine; this was not the Miles I expected to hear.
Head Hunters, and Weather Report were two groups that impressed me with this new music. Although we try to communicate music with words, it's impossible; the only thing that can be communicated is how this music affected or impressed "you", and that's the only person you can speak with any authority for. "Sextant" was the Herbie Hancock album that impressed me, it really blew me away; I even liked the cover art.

Weather Report, "I Sing The Body Electric" was the first album I acquired by that group, it took me to another world; the music was not of this universe, it took me someplace I've never been before, and I liked it.

Frogman, both "Oregon" and Chick Corea are well represented in my collection.
Enjoy the music.
