Here's the basic rhythm riff to Trail of Tears, off Testament's newest, -Low-.
(Not many people have even heard about this release, Alex Skolnick is no
longer in the group, and instead they got James Murphy from Cancer.)
I had not the time, nor the skill to tab the rest, so this is what I've got, I
figure it's better than nothing, right? :)

riff X:
[E--------------------------------------------------
B-----1--------1--------1-----1--------1--------1--
G--------------------------------------------------
D--------3--------3--------------3--------3--------
A--5--------5--------5-----5--------5--------5-----
E--------------------------------------------------

riff Z:
E--------------------------------------------------
B-----0--------0--------0-----0--------0--------0--
G--------------------------------------------------
D--------3--------3--------------3--------3--------
A---5-------5--------5-----5--------5--------5-----
E--------------------------------------------------]

You just play riff X, into riff Z, back to riff X, so on, so forth. Like I
said, it's not a whole lot, but it's a nice little bit.
