Spanish Guitar

lest I forget: Bebo & Cigala "LLagrimas Negras"
which isn't a flamenco album per se but a flamenco singer paired with a Cuban jazz pianist doing classic love songs from the 'golden era' of popular latin love songs. This will give you an idea of what a flamenco singer sounds like.
Bebo at 80+ is truly tremendous (he is chucho valdes' father).

All good suggestions, although covering a range from older, classical Spanish through Latin American to Noveau Flamenco, three quite different flavor mixes. I second Swklein's suggestion that Naxos label is a great, economical place to look.

Consider the 4 CD set on Deutsche Grammophon by Narcisco Yepes, entitled 'Guitarra Espanola'.

Liona Boyd's 'El Camino Latino' has to be one of the sunniest in a sort of cheerful noveau Latin American way.

Paco de Lucia 'Entre Dos Aguas' (Philips)

John Williams, 'The Seville Concert', featuring 'Concerto de Aranjuez'

Yes, there is a real difference between the neo flamenco people like Jesse Cook, Ottmar, etc. [which I do like] and the REAL guys like Montoya. Some might say it's like comparing Kenny G to John Coltrane, although I think that's an insult to the neo flamenco artists and not completely fair either. But there is a difference.

Real flamenco people also get pissed if you associate the Gypsy Kings with them. Maybe because they're actually from France or because of their worldwide pop appeal. I like them too. But then again some of these people don't think anything is true flamenco unless it comes from the caves of The Sacramonte. Suffering seems to be a big part of flamenco.

There's also a lot of great non-flamenco Spanish guitar work.

Amazon.com has a lot of nice neo flamenco compilation discs such as Flamenco Fire and Flamenco Passion with artists like Ruben Romero, Strunz & Farah, Jesse Cook, Ottmar Leibert, etc... I'll definitely have to check out the Gino D'Auri XRCD.

The thing I like about music from Spain is that it has so many great Gypsy [Middle East & Indian] and North African influences. Rich and passionate!

Yes; Gino D'Auri's 'Flamenco Mystico' has a stunning version of the classic Recuerdos de la Alhambra.

Jlamb has a good list there but I believe Paco Pena should also be a must listen as the world's first Professor of Flamenco Guitar and one of the all time great Flamenco Masters.
