Vallejo gives great recitations of Latin, better than the majority I've heard yet; he uses a medieval/Italianate pronunciation. And speaks it with exceptional fluency and grace. His files used to be available through Vivarium Novum, but that site is now down.. His recitations of Ciceronis Orationes in Catilinam are available elsewhere now though (included below), as is Caesaris Liber Primus de Bello Gallico. Unfortunately, I cannot seem to find any other of his recitations at the moment. I believe De Republica was one of them; and possibly one or two others. If anyone knows of them, please let me know!
