The Owsley Stanley Foundation of Grateful Dead fame has just released ‘You’re Doin’ Fine,’ a sumptuous three-CD set capturing John Hammond at two 1973 concerts at the Boarding House, a small club in San Francisco. The sound man was Owsley Stanley who invented the Grateful Dead’s wall of sound technology.

“I didn’t know that Owsley was recording that show. I was told he was the sound man, but I didn’t understand the significance of it. I mean the sound is great.”

“Our approach to it is to make it authentic, and we do that all the time. People say, ‘You guys sound like the record, only better.’” Interview with Dusty Hanvey, who has been the Grass Roots’ lead guitarist and one of their vocalists since 1984.
