For the benefit of Larry, if I were to ascribe a one word term for classifying the Grateful Dead, that word would be "psychedelic".
But since one word is never enough to describe any entity as singularly unique as the GD, I would expand that definition to include "American, jug-band-style, rock and roll roots oriented psychedelic outfit."
I think it was promoter Bill Graham who said about GD, "They're not the best at what they do, they are the only ones who do what they do."
I could package up the entire 1970's decade of live Grateful Dead and recommend it all. A local talk show host, in the midst of an unrelated discussion, asked a caller to make a choice: go back 40 years in time and use the experience/knowledge you now have to live those 40 years again, or begin living at the age you would have been 40 years ago starting right now. The host stated he would prefer the latter, because who would want to live through "stagflation" again and so forth. I would prefer the former, because I would want to see a lot of these shows again (not to mention Pink Floyd, Led Zeppelin, The Band, and others too numerous to mention).......in addition to gathering up all of that old tube gear because transistors were better, and so forth.
For the uninitiated and curious, I recommend the live release "One From The Vault", August 13, 1975 at the Great American Music Hall in San Francisco. This is a very clean, well presented recording, offering a good mix of straightforward, easy to enjoy material with enough "psychedelia" to show you what this band can really do in this element. Put simply, the band just cooks and is very focused.....almost TOO focused for thier norm, but the energy that prevails from what was a very important performance (first performance of material from Blues For Allah at an invite only show for 500 people) translates well through the recording. This was my first GD live tape. I wore it out, so you can imagine that I was quite happy when it was released as an official offering.
In the cassette/analog days, many would "skip" drums/space by the convenience of how that was usually laid out on the tape. The good "editors" would lay that show out so that drums was last on side A and space was first on side B, so you could flip the tape when drums started and end up where space ends. The spot where the taper chose to edit could be a topic of debate amongst the exceptionally choosy/geeky collectors, as did the specific sources/"generations". Those were the days.....
To me, the Grateful Dead are as American as hot dogs and apple pie. They exemplified "freedom of expression". The symphonic "takes" and spinoffs/"logical musical extensions" don't surprise me in the least - I suspect that this music will be played, sang, and otherwise enjoyed for generations to come.
If you enjoyed hearing the GD do "space", then you must have been at the show. You had to be there
