I always thought In-A-Gadda-Da-Vida was kind of a heavy metal joke. I had no idea that Iron Butterfly were so influential in the rock world and so many artists credit them with giving them inspiration. I also had no idea that Taylor Kramer, the bassist was a high school drop out who went on to be an engineer for the Departmet of Defense and was an originator of facial recognition technology (IN THE 1990's!) to help find missing children and adults. Hear his very twisty story here.
