Sam omits to mention that Bilbao 00:00 is a double CD with MANY guests - including Boutine Souriante. A couple of tracks let down (IMO) with over-sylised singing (see my comparison of Susanne "live" with her CD) but non the less highly recommended.However the best of all Spanish CDs of recent years (and yes, we do have all those listed by Sam, and a few more) is that of Pancho Alvarez, "Flocencio, O Cego Dos Villares". For information see: http://www.folkworld.de/12/e/pancho.html
If I recall correctly it was FolkWorld's "record of the year" a couple of years back . . and thoroughly deserved; it really is a stunning album. (No "naff" singing, either!)
