As one of the most reliably awesome outfits in heavy-metal history, English sword masters Saxon mark 40 years of riffing and rolling with Thunderbolt. On their 22nd album (!), they pay tribute to their fallen touring partners Motörhead with the rip-roaring "They Played Rock and Roll," add some surprising guest death-metal growls courtesy of Amon Amarth's Johan Hegg on "Predator," and continue their proud tradition of supercharged songs about transport with the anthemic "The Secret of Flight" and the slamming "Speed Merchants."
