If we're just talking favorites.
Moody Blues w/ The Nashville Symphony at an outdoor Balloon Festival would probably be in the top 5.
Metallica at Bonarroo in 2008.
Rob Zombie with The Necromantics
Billy Joel's Piano Man Tour
Volunteer Jam V
I know there's more, but trying to remember them isn't easy, my memory is a blur.
Billy Joel and Moody Blues on my Bucket List.. but so was some others who I will never get to see..
