Most compelling are the rare and sometimes unusual collaborations. Joe Walsh and Taylor clown around on "Steamroller Blues," and Booker T. & the M.G.'s back both Joe Walsh on a rollicking "Rocky Mountain Way" and Los Lobos' David Hidalgo tearing into a sizzling "The Neighborhood." Clapton and J.J. Cale share the stage as do Clapton and Carlos Santana, and a show-stopping blues summit with Robert Cray, Jimmie Vaughan, Hubert Sumlin, B.B. King, Buddy Guy, and Clapton is a treat for all involved.
There are some shortcomings. The event isn't presented in chronological order--different stages, days, and backing bands are shuffled with Clapton's own set scattered throughout--ZZ Top's closing is a bit anticlimactic, and there are many omissions due to time constraints. But every act rises to the occasion, and this expertly recorded and shot DVD gives the viewer a front-row seat to a once-in-a-lifetime experience. --Hal Horowitz
