Concierto de Aranjuez by Regino Sainz de la Maza, Guitar with the Orquesta Nacional de España conducted by Ataulfo Argenta.
CD $14.95 The Premier Recording. This was recorded in the early 1940's.
Having heard a dozen different performances of the most popular piece for guitar and orchestra, I find this orchestra to have a delightful and lively ensemble spirit. It is definitely my favorite of all orchestras.
