Which other guy? That James Hetfield? Have you seen their TABS? That guy's an excellent rythm guitar player, dude. I mean, I haven't listened to ALL of their songs, not even a small portion, actually, James is an awesome guitar player.
Anywayz, Johnny Cash really is a guitar hero, IMO. Listen to his last album and tell me different, you know? That guy takes acoustic guitar to the next level, which is something that probably won't happen for a very long time.
On a side note, as I was listing the names of my favorite players (this list can be found up above.

), I forgot to mention Zakk Wylde. I hate myself for this, you should know. Zakk Wylde, to me, is a fricken guitar God. He's an excellent acoustic player, but man he can tear it up on his tunes. Listen to 'Stoned and Drunk' if you don't believe me. He's got a good sense of melody, and he takes his songs where you least expect them to go, which is a LOT more than I can say for most of the 'musicians' out there these days.
Okay, I'm done until next post.
