From the opening metallic whoop of the title track, Fireball is an album of superlative heavy rock power and progressive intent, from a band delighting in their collective abilities. The relatively chipper and folky “Anyone’s Daughter” aside, it’s a collection in which the five players take a lead role, each instrument either weaving around the others and jostling for attention (“The Mule,” “No One Came”) or coming together in unison to deliver riffs of crushing intensity (“Fools,” “Demon’s Eye”).
