The great, classic bands have an unmistakable "trademark" sound. The Doors, the Stones, the Pretenders etc.: One measure and you know who you are listening to. By early 2018, Band-Maid had firmly established their own trademark sound. It had echoes of those three and other, heavier bands like Guns 'N Roses and even Metallica, with a jazzy, funky underlay unique to Band-Maid. Now they began to experiment with more sounds and structures from outside mainstream rock.
