It's hard to look back to the days of classic rock for inspiration without being pegged as a mere imitator. Black Mountain are clearly disciples of genre forefathers like Led Zeppelin and Black Sabbath, but they bring a certain harmonious folk element to their work that helps to keep it from being mere derivation on the themes of those bands. Naturally, you're going to find that kind of heavy stomp that is synonymous with Zeppelin and Sabbath, but Black Mountain do things their own way, and they are given to long, proggy outings over tighter rock 'n roll. Wilderness Heart is a blend of heavier, driving rock songs and ominous folk numbers. Most songs feature both of the bands' singers, both talented and carrying the necessary bravado for their roles, but I wish that when singing in unison that they would sing more harmonies, where instead they are usually singing the same melody in a different octave.
