Query: Crossroads 2007 DVD is great!

The two disks of the DVD contain a wealth of extraordinaryguitar playing. Many guitarists from the 2004 DVD are included,like Robert Cray, Doyle Bromhall, B.B. King, John McLaughlin,Robert Randolph, John Mayer, Hubert Sumlin, Buddy Guy, Los Lobos,Jimmy Vaughan, and Vince Gill (and of course, Eric Clapton).Several guitarists appear on the 2007 DVD that weren't on the2004 DVD, like Derek Trucks, Susan Tedeschi, Jeff Beck, SteveWinwood, Sonny Landreth, Sheryl Crow and Willie Nelson, allwelcome additions. A few guitarists, like Joe Walsh, JamesTaylor, Steve Vai, ZZ Top, J.J. Cale and Carlos Santana fromthe 2004 DVD don't appear on the 2007 DVD, but this is probablydue the way the two events were scheduled. If you like to hearthe guitar sing, this DVD is for you.
