I will add this of JK, which I've said in other threads...
He is being given space to be JK within Furthur. What greater honor could be bestowed on any freakin' guitar player, who aspires to play in the Garcia style? He paid his dues heartily to the material. He brought joy in the process. The last time I saw The Dead play it was dour. One of the drummers was on his feet prodding Bobby to move out of a jam. Insulting. Uninspired. Warren was the high point of the nights, and I didn't like him at all in that role the year before. Bob hardly played.
I saw the Grateful Dead more than 100 times, beginning in 1981. There were some Cosmic Awesome Thrilling Life-changing and Exhaulted times. When I am honest, as has been stated by many before...in the latter years we forgave...and hoped for an evening of magic....maybe even a 3 song run. C'mon Boys...give us a Help>Slip>Frank with gusto!
When I saw a 3 night Furthur run in Eugene, OR last summer...Phil had perma-grin...Bob played almost all night for 3 nights instead of rig-fiddlin' (and played awesome).
..and John K. showed us Jerry...tipped his hat to Jerry...reminded us of why we love this music...and he participated in an experience which (to me) revivises & reinvents the music we all cherish.
Everyone is entitled to their opinion of anything. That's what the internet has brought us (good or bad.) My 30+ years of empirical experience leads me to these statements. JK has earned his place...and I bet if you asked the boys...they'd say the same thing.
...of course I won't get to see them until the end of Sept, and it all might've changed.
Peace Brothers & Sisters.
