It’s about drumming on the steering wheel or strumming that air guitar. It’s the pure raw adrenaline that surges when you spin up that brand new record. It’s the goosebumps when David Gilmour hits that second solo on Pink Floyd’s Comfortably Numb, when Dimebag Darrell rips the solo on Pantera’s Floods. From the shrieking vocal harmonies on Iron Maiden’s Powerslave to the the crooning of Peter Steele on October Rust, we simply have an affinity for the thing that has moved us through the best and worst times in our lives.
