"The debut Paul Butterfield Blues Band album was the first "real" Blues music I heard."
We must be close in age because my friends and I had a similar experience. I was a nascent guitarist who was totally bowled over by Mike Bloomfield’s skill. His sound and approach was widely admired and emulated. Early electric Jerry Garcia owes a debt to Bloomfield. The "thin wild mercury" sound of Bob Dylan wouldn’t have existed without Bloomfield (and Robbie Robertson). And of course, Bloomfield was someone else whose life was cut short because of drug abuse.
In the late 1970’s, The Lone Star Cafe, in NYC hosted Richard, Rick and Paul on a fairly regular rotation. Along with Dr. John, you could see "roots" music for a $10 ticket and two beers.
