One is John Hammond, the other isn’t.
The John Hammond this episode of Slipped through the net is dedicated to, is not the John who gave artists such as Bob Dylan and Bruce Springsteen a kickstart in their career, but his son. John Junior may not be as famous as his dad, but he has been holding his ground as a guitarist and interpreter of blues and related styles since the early sixties. In the early 2000s he released Wicked Grin, a whole album featuring Tom Waits songs, which, surprisingly, the man himself also contributed to.
