What Is The "Greatest" Prog Rock band?

If you think the hackneyed and contrived music of Opeth is better than TOOL, then TOOL is simply over your head...

I wouldn't describe Opeth as 'hackneyed and contrived' at all.

Both Opeth and Tool should be applauded and respected for their ability to redifine their own sound and stretch the boundaries of the genre they have been placed in by their reviewers.

To be able to produce consistently good albums over a long and varied career, that continue to bemuse and enthrall in equal measure, is something both bands can be very proud of.

As a survivor of the sixties and a pro player from the 70's, and not racist at all, Miles Davis' lineup for Bitches Brew is the most progressive and influential album from these art-rock times. Being influenced by Jimi Hendrix, Miles wanted to make a similar statement. He invited Herbie Hancock to play keys, only making him use a Fender Rhodes, an electric piano, for the first time. Herbie later found his own synth fame. Miles also had Chick Corea on keys, who went on to jazz-rock fame with Return to Forever. Just look at the other musicians who all went on to greater musical styles and fame after that musical eruption. John McClaughlin on guitar, for example.
If all you do is add up the various album sales and band poll wins, this album is it. What Jimi did with his own overdubs, and Stevie Winwood on keys, Miles created with live musicians. Electric Ladyland and Bitches Brew, what a two.

John, I couldn't agree with you more on your observations and analyses in this post. In fact, one of the great tragedies of Hendrix dying at such an obscenely young age as he did is that Miles Davis wanted to get together with him and produce an album--wow! One can only imagine and dream about what a dynamite team they would have made! If I'm not mistaken, I believe that Bitches Brew owed a lot of its inspiration to Electric Ladyland. And I am pretty sure that at some point, Miles would have--privately or publicly--acknowledged this "debt" to Hendrix. Two more awesome artists and albums in the annals of music--any music-- history would be hard to find indeed.
