All About Jazz has a great review of a a relatively new Johnny Winter DVD (Nov. 2008) featuring a collection of concert footage from Connecticut, Germany, Denmark, and London intercut with rare interview clips.

The last paragraph of the review about sums it up:

It has been said that it’s the music that matters. It truly does. The music contained on this DVD cements Winter’s reputation as one of the best blues guitarists and performers of his generation.
