I went last week to see Plant and Krauss at Forest Hills Stadium. I have seen Plant numerous times over the years. Definitely not as hard rocking as in the past but its always worth seeing him and what he does to change up music. They played 3 Zep songs, Rock and Roll, Battle of Evermore, and When the Levee Breaks. Plant has mellowed over the years but I will say his voice is still there. Great show and no hot pretzels
