The jazz bassist shares resonant stories in an interview and performance.

There may be no greater ambassador for jazz these days than L.A.'s adopted son Charlie Haden. Haden's nearly 40-year career has encompassed such genres as free jazz, Portuguese fado and vintage country -- the last of which is featured on his latest album, "Rambling Boy" -- not to mention a consistently revolving roster of sidemen and bandleaders that reads like a list from some imaginary jazz hall of fame.

But Haden is first and foremost a music fan, no different from the people who turned up for the recently opened Grammy Museum's second evening of conversation and performance (Brian Wilson was the subject of the first). And that's what made his conversation with museum executive director Robert Santelli so memorable Wednesday night as Haden told story after story from jazz's most fertile period.
