Late to the game, once again reviewing an old DVD-A here in 2017
Surround mix & audio quality are impeccable, but the songs on Two Against Nature don't blow me away like other Steely Dan albums. I'll go with a net 9.
I'm building my Steely Dan-related surround library - presently have Gaucho (SACD), Two Against Nature (DVD-A), Everything Must Go (DVD-A), and Morph the Cat (DVD-A). Waiting for delivery of The Nightfly, and still looking for a bargain on Kamakiriad before I pull the trigger.
I surely wish the earlier albums were readily available in surround! My favorite is Can't Buy a Thrill but I'd buy them all if I could.
