Probably not what you are looking for but the festival at Ortigueira has top notch performers and has the great advantage of being free.

As far as Antequera/Malaga is concerned this is hard. There may be some flamenco in the area but it would be hard to locate at a guess.

My local pub in Almunecar about 60 miles away had spanish music nearly every night of the week from local gypsies and others. The highlight of my time there was an evening with Gerardo Nunez. There is a flamenco festival there (or was) which was why Nunez was there - around June/July. But having taken a look I couldn't find out when it is.

Sorry Jack best I can do.
