Not trying to be closed minded, but I don't care for the "metal" genre. Led Zep, iron butterfly et. al. may have been precursers, but i don't think they really fit in to todays understanding of "heavy metal'. Had The New York Rock Ensemble continued, they may have evolved into the PREMIERE heavy metal band, the influence is obvious an some of their tunes. We would have probably had much more talented metal bands today if they had to compete with Michael Kamen, who now does mostly movie work.
