This day in music history.

July 20, 1968, Iron Butterfly's second album debuts on the U.S. charts. "In-a-Gadda-da-Vida", featuring the 17-minute title track would stay on the chart for the rest of the year. The song "In-a godda- da- vida" (with 2 and a half minute drum solo) made it to number 30 on the pop chart. Some consider Iron Butterfly to be the first heavy metal band and In-A-Gadda-Da-Vida" is considered to be the song that ushered in the era of acid rock.
