Magnum II is the second studio album by British melodic rock band Magnum. It was released in 1979 on Jet Records. Magnum II followed on from the success of Magnum's debut album, Kingdom of Madness. Recorded with former-Ten Years After bass player Leo Lyons, who had success with producing Phenomenon, Force It and No Heavy Petting for UFO. As with debut album Kingdom of Madness, much of the material on Magnum II was already written and had already been previewed in Magnum's live set and were suitably "road tested". The album, however failed to chart on its release in October 1979.
