Not too many Spanish flamenco guitarists dedicate pieces to Scottish psychiatrists, which is what Eduardo Niebla did on Sunday night with Ron- nie, written, he said, in homage to the late R.D. Laing. But then Niebla, born in Tangier, isn't entirely Spanish and the music he plays isn't entirely flamenco.

Like the great Algerian-born guitarist Pierre Bensusan, he's not easily categorisable, though his roots and inspiration are recognisably Spanish. Like Bensusan, too, his playing is technically awesome - the quickness of the fingers sometimes bewilders, if not deceives, the ear. However, he lacks Bensusan's subtlety and poetic imagination, and this concert had too little dynamic variety and too few textural and emotional shadings.

At times - quite a lot of times - he sounded like Mark Knopfler on sangria, a sultan of Spanish swing, with those trademark accelerating riffs we all recall from Dire Straits, leaving the packed Aungier Street venue roaring for more and this reviewer yearning for less. Only in the R.D. Laing piece did he slow up, quieten down and allow the soul room to breathe.

Still, there was no denying either his brilliance or his intoxicating rhythmic allure, the latter helped considerably by his partner, named in the flyer as Victor Unokovsky but introduced by Niebla as someone else (the name was hard to catch), who seemed content to assume a supporting role throughout.

The audience loved it all, even if their enthusiasm sometimes outstripped their knowledge. At the interval one young woman recalled being in Seville last January and "going to this terrific flamingo place". Pink, no doubt.
