I saw Heaven and Hell with Coheed and Cambria last night, got a free ticket from a promo for buying a ticket to the Dethklok show in October.
Coheed was great, they played a nice cover of Iron Maiden's The Trooper. They mostly played songs off of their last 3 albums, don't think they did any songs off of Second Stage Turbine Blade though.
Heaven and Hell was amazing. Dio, Iommi, Butler, and Appice were all great! They played songs off of The Devil You Know and all of the Dio fronted Black Sabbath albums.
