Just before he died in 2009, Joe Castro sat down with his son James to listen to some tapes. The reel-to-reels were full of Castro's own decades-old recordings, in which the jazz pianist jammed with his contemporaries.
"It was kind of like a shock," James says, "because right when we put the first tape on, it sounded like it was recorded yesterday."
Father and son went through more than 40 hours of tape. James says he was used to hearing his dad back up other musicians.
