Range is something music critics put a lot of emphasis on, and this isn't without warrant. A band's ability to cater to a broader spectrum of people is a needed skill in today's love it/hate it climate of preference. Though all music could be said to be progressing today, for some reason heavy metal produces the most consistent visible evolution. Perhaps this is in part due to the genre's adolescent stigma. Needless to say, heavy metal today is transcending something of a stagnated state.
Black Cobra is a band with this range. They've played with everyone from The Sword (Guitar Hero, right?) to Kylesa. Feather and Stone clocks in at about a half an hour. What you can expect is a good effort deserving to be heralded alongside the dynamic and critically acclaimed Torches, Baroness' and Mastodons of the field. These bands are so good because they can synthesize the diehard Lemmy-inspired nostalgia of yesterday with the sort of arms race of "Heavier, Louder, Slower" towards metal supremacy. Black Cobra walks that line, skillfully.
