It's like he's forgotten why he got popular in the first place. Him in DGD was something different, now this is just him doing bad covers of good songs. I could hunt youtube for better covers than this.
Is that Garren? because the guitarwork in all these covers is solid.
I would guess either Garren or Kurt did the guitar. I didn't like that Cry Me A River cover at all though. I liked the live versions he's done but that was just meh. Sounded like he was all over the place.
