First time I heard the Allman Brothers was probably in 1969 opening for the Grateful Dead at the Fillmore East. I saw them a couple of times after Duane and Berry died and they were good but a very different experience. I saw them years later with Warren and Woody and they were really good, back to the original sound. I lost interest until I read the reviews on this site. I got Hitting the Note which I really like and was totally blown away by One Way Out. I am really happy for the band that after all these years they have really raised the level of their intensity.
I have been listening to some of their older live albums with Duane and Berry. Duane of course was unbelievable and Berry was flat out great with them.
When I get a chance I am going to Blockbuster to see if they have the DVD of the Beacon show.
