The singer songwriter is generally under appreciated. Why? I don't know, but Carole King & James Taylor's concert DVD; Live at the Troubadour is pure singer songwriter heaven. It's not about edge or icons it's a couple of great singers with some great songs, singing, simple as!
It's just lovely nice music performed with no frills by two artists who, decades after their popular peak, still have the magic.
