Great thread!
I already had some of the recommendations, but bought several more. All were quite wonderful!
I especially enjoyed the RTF (Return to Forever) returns, Live at Montreux performance. Although I was familiar with the individual RTF performers (Corea, Clark, Di Meola and White), I had not heard them perform as a group. It would be an understatement to say that I was impressed. Their ability to tightly mesh together as a single entity, but stand out in each of their own disciplines, was a real treat to see and hear.
Additionally, as a CTA (Chicago) fan, I really enjoyed the Chicago and Earth, Wind & Fire: Live at the Greek Theatre DVD. One wouldnt necessarily think that the two together would be a good combo, but boy, it was! On the DVD, each group performed separately and then together. For the fans of either or both groups, what a great party DVD!
The 25th Anniversary of The Rock & Roll Hall of Fame was also a real winner!
