Wow, that's a trip. I knew he sounded different in 01 but I didn't realize just how much. It reminds me of that band Zebra from the 80's. 06 kicks ass though - his voice is stronger than even '92 - in fact, the whole sound of the band is just massive, like a wall of sound. They should scrap the studio recordings and put out a live album. The live versions sound better than the leaked demo's.
I completely agree that his voice sounds better then ever.
