Recorded last year at the Fox Performing Arts Center in Riverside, CA, this is the first televised concert featuring Steve Martin playing it straight – except for some funny between-songs patter – as he plays the banjo and works through his old and new collaborations with singer-songwriter Edie Brickell and their backing band, the Steep Canyon Rangers.
