So, my nephew-in-law Frank put together a list of albums that had an affect on his life. Based on his upbringing and his locale (New Orleans), his may be a bit more eclectic than mine. I'm still not sure of the order of these albums, and there were others that were on the list and bumped off, then put back on. Mine are mostly late 60s and early 70s, but that was the decision making period of my life. It's a pity that the decisions made in your late teens have such a large impact on your later life.
