Concert or Flamenco at Palau de la Musica?

Dracula music? Hmmm....

I'm familiar with Edgar Winter's Frankenstein, but "Dracula music" is new to me. I'm so out of it.

This does not precisely answer your question, but it may give you a little more data, short of an actual review of a show:

You can't say "the show at the Palau". It's similar to saying "the show at Carnegie Hall" or "the show at Van Wezel Hall" or "at OCPAC". In the sense that a stage Flamenco show is not precisely the same as a close-up Flamenco performance in a small nightclub, it's a reasonable nuance to ask about.

First of all do not miss the Palau.. it is a beautiful building inside and out. The design is extraordinary.
They offer tours if u decide not to attend a performance.

Not going to give any opinion on flamenco -I myself don't like it- but regarding a visit to the Palau, just some thought hereafter...

• A guided tour of the Palau de la Música Catalana (which is its full name) vs attending a performance, differs greatly. In the first case, you're given a full visit of one of the gems of Modernisme arts & architecture in Barcelona, seeing most of the Palau and getting in-depth views of many of the halls and rooms with a knowledgeable guide. Attending a performance gives you the possibility to see only bits and pieces, mostly the entrance and the main hall only. On the other hand, a performance gives you the opportunity to experience one of the marvels of science as the hall was designed to have an impressive acoustic regardless in which seat of the main hall you're seated in, even if you're behind one of the few columns there are.
• While indeed flamenco is alien (or "imported" if you must) to the heritage and traditions of these shores, this is Catalonia after all, in the same manner one can see a quality performance of say, Russian ballet or Irish step dancing, in NY, from time to time, one can also see a great performance of flamenco in Palau de la Música since the Hall hosts performers from all over the world on a regular basis. Whether you'll "catch" a good one or not I suppose it's a matter of debate
• As mentioned above as well, flamenco is a genre which offers different "types" of performances, from the most visual spectacles with many dancers to the most intimate ones with one dancer. Equally, some flamenco performances are about music and singing rather than dancing so you'll find one or two guitarists and one or two singers. For these latter type of performances, the smaller the scenario the most intimate it becomes and the most "feeling" it conveys -if you catch my drift. So for this type, a place like Palau might not be the best scenario.
• By all means, if you have the chance to go to Seville or Madrid, somewhere where the autochthonous culture is indeed the Spanish (Andalucian and Castillian) culture, which is not the case here in Barcelona, wait to attend a performance there and you'll have many more chances to stumble upon many traditional close-up flamenco performances in a small nightclubs. After all, there you'll be in the cradle of this form of musical arts.
• If in Barcelona, whatever you do, I personally would avoid the touristy "flamenco dinner shows", not only the food is outrageously bad, but those that do like and understand flamenco can tell you how tacky and bad are their shows. These are true shameful tourists traps. Some say, well, I've never seen flamenco so at least I can have a glimpse there... well, do it at your own peril, but know that, for the most part, you're not going to see "flamenco", you're going to see a Disneyesque show designed to get you drunk and keep ordering bad food charged at expensive prices.
• Last thing: not referring here to Corrine but to some other posters of the forum (in other threads I've seen): it's FLAMENCO, not flamingo, LOL! :)))

Enjoy!

PS: You'll see sometimes I refer to the place simply as "the Palau"... note that the name is, as mentioned at the beginning, Palau the la Música Catalana and it should be referred as such in order to avoid confusion (Palau just means "palace" in Catalan, the local language). However, when in a conversation, once you've initially established you're referring to "Palau de la Música Catalana", is all right (in Catalan, anyway), to continue the conversation referring to it as the Palau ('the Palace').

Tim - thanks for the link to the other discussion and Enric - thank you for the detailed information.

It sounds like a wonderful sight not to be missed and I have the time so I'll do both activities -- see the Flamenco performance and take a tour!!

Having done both, saw different flamenco shows in Sevilla, Madrid and also Barcelona, I would do both:
-See a show at Palau de la musica catalana as this place is just wonderfull.
-See a flamenco show in a small venue such as Palau Dalmases. A great small venue with great artists every night

We couldn't get a tour of Palau de la Musica nor attend a performance. However, we walked to it and wandered a bit inside. It's incredibly beautiful and interesting. I would urge people to at least pay a quick visit if that is all they have time for. There are even some poster boards with historical information. It's stunning both inside and outside, my only frustration was that you can't get a good picture of the exterior because the neighboring buildings are so close.
