Audio of the Van Halen brothers performing Black Sabbath's "War Pigs" back in 1972 has surfaced online!
According to the description on YouTube, it was possibly recorded at the club Gas Company in Pasadena, California, in 1972.
If that's the case....it might be one of the earliest known recordings of Mammoth, which is one of the early versions of the band that would eventually become Van Halen.
Something else that's really cool about this find....the late Eddie Van Halen is handling lead vocals!
Give it a listen below or over on YouTube.
