First, I have to mention the opening act, Bettye LaVette. Great bluesy singer that to me was somewhere in-between Gladys Knight and Tina Turner. Probably closer to Tina. Her band was great also. Two or three hours of her music would have been well-worth the money. Her music and her versions of other's songs were all well done. Perfect choice to set the mood.
As to Robert Plant and his Band of Joy, it was a thrill and a joy to witness. They started off with 'Down to the Sea' from his Fate of Nations album. Sounded great. They also played quite a few songs from the Band of Joy album (which I will buy when it comes out). He played quite a few Zep songs, such as Misty Mountain Hop; Houses of the Holy; Rock and Roll; Over the Hills and Far Away; and my two favorites of the night, Tangerine and Thank You.
One thing in particular that really impressed me was that Plant stepped back and played harmonica or sang back-up while other band members took the spotlight on at least four or five songs.
Don't miss this concert if it comes your way. I'm sure this isn't Plant's last tour, but it was well worth the money. His voice is still wonderful and his band is awesome.
