I can't get over how amazing Chester is sounding. Seriously. It's most apparent on songs like In The End, Numb and Breaking The Habit (the bridge! wow!). He was never bad at those songs but now he just sounds perfect. I'm no longer wincing at songs like Leave Out All The Rest either. *mancrush*
I don't want to get into Chester's personal business, and I don't know exactly why he has regained top form, but I think his decision to quit some old bad habits has definitely contributed.
