I was there

I saw the ABB twice that summer: New Orleans Saenger Theatre and Boston/Mansfield Great Woods.   Loved what Derek added.  Love the True Gravitys from that summer.    Derek really played that one so well and we had a great ying/yang in tone between Derek & Dickey.    The tapes aren't always flawless for entire shows (and Warren's background/harmony vocal absense during this period is felt), but I pieced together a full CD of great renditions from that summer I used to play a lot.   Thanks for sharing.

@hotlantatim I saw a Las Vegas show that was flawless to my ears. Susan opened and Derek had great solos on Blue Sky, True Gravity, Dreams etc. 

Dickey had a long high energy solo at the end of Ramblin' Man and Dickey and Derek both were playing extremely well. I have some pictures I shot and have a couple where Derek and Dickey are going at it very close to each other and my favorite electric is a good Les Paul but Dickey's old 1956 Fender Strat sounded real good the entire show. 

Dickey later said in an interview he was playing his old Strat right now as his main stage guitar because he is mad at Gibson for ignoring him. Not sure what that was about. 

I would have never guessed that in less than a year Butch recruited an irritated Gregg to help him throw Dickey out of the band. 

As I look back over the entire history of the band, Dickey's sound, guitar style and original songs, especially on Brothers and Sisters, are the main reasons the Allman Brothers Band survived the loss of Duane. 

Poor Butch never got over his anger and dislike of Dickey. Gregg did and he and Dickey were brothers again the last years of Gregg's life:)

Man, young Derek looks like a baby. To think he was meeting Susan then, would get married a couple years later and now has college-aged kids makes me feel really old  

Dickey’s  solo on True Gravity is ethereal. He is in some kind of zone that only Dickey can be in. The soft picking and then the little run @ 8:45 is magic.
