"This is the live performance of Veteran of the Psychic Wars by Blue Öyster Cult, from the Extraterrestrial Live! tour ca 1981, recorded in Pembroke Pines, FL and released on the 1982 live album of the same name.
"It contains one of the all-time coolest extended instrumentals in rock and roll, a guitar solo journey with spot-on accompaniment that rises and rises and rises in intensity until it feels like a laser beam, a cathartic blast to break the weight of a heavy song that would have surely melted a few faces in that lucky audience."
