I work with my computer for at least a few hours every day, and I've gotten really familiar with the concerts at www.sugarmegs.org. It's almost shocking how vibrant and alive the older stuff sounds from the late-Duane Allman Brothers, the 1st-edition Mahavishnu, the glory years of the Grateful Dead (1972-1974). Back then, bands were not trying to "put on a show", they didn't give a rat's ass about hitting exactly the right notes or the right facial expressions - they were trying to grab hold of the universe and warp it for a few hours. Dial up the Allmans last few recordings with Duane, 71-8-27 and 71-9-16.

"Elizabeth Reed" starts at 20:04, Duane's solo starts at 27:59. It's completely different than the live album version, and sure he hits a few clams. But it KILLS, in a way poor Alex Lifeson could never even understand. Duane's not even trying to "put on a show" - he's got higher goals. The triumph of robot rock 'n' roll has been a sad thing... If you listen to a sugarmegs concert of the "new" Allmans, post-2001 with Warren Haynes & Derek Trucks, it sounds extremely competent, well-played - and tame and dull as shit.
The difference between Page on his best nights, and McLaughlin, Garcia & Allman on their best was that *you get good at what you work at.* Page was a genius songwriter, arranger, engineer.... when he tried to veer into hippieland ("Dazed and Confused"), ugh. The others very specifically practiced and worked towards using their guitars as mind-control weapons. :evil4:
My favorite bands and players of this new century all record live with the band for the most part, at least the base tracks. Listen to OHM, Julien Kasper and Oz Noy, and see if they sound different to you than Joe Bonamassa, John Mayer or any of the other meticulous "heroes." Knowing how to improvise is no "gift", it's a result of a lot of hard work.
