Great review, although I'd have to disagree with the following:

That direction, arguably, is back in time, as this “Sand” recalls its 1999-2000 cock-rock glory.

To me, the Sand jam from last night has little in common with those from the 1999-2000 era. Those were all about the ambient, looping, Trey-in-the-background-or-occasionally-on-keys jams that focused on groove and texture. Last night's Sand jam, on the other hand, was a vehicle for Trey to fuck our faces with his guitar, and fuck our faces he did. It was more similar to the Walk Away that followed than any 1.0 Sand, IMHO.
