Hong Kong Sinfonietta with the Romeros City Hall Concert Hall Last night only The fact that Rodrigo's Concierto Andaluz, first performed in 1967 by the Romeros, only had its Hong Kong premiere last night is presumably due to its rare requirement for a guitar quartet. The performance featured some of the Romeros original line-up - founded by Celedonio Romero and his three sons in the 1960s - though two members have been replaced by third-generation Romeros. The quartet were fluent in reflecting the Spanish flavour of the music, and it was a joy listening to their rapport. Their admirable camaraderie never compromised individual members' flair. The two sublime encores, one by Celedonio himself and the other a flamenco improvisation, deservedly won whole-hearted applause from the audience. The orchestra - the Hong Kong Sinfonietta, conducted by Yip Wing-sie - was not a match for the guitarists, and they often sounded a bit timid. Rodrigo's Concierto de Aranjuez performed by Pepe Romero was exhilarating and fluent, although sometimes not as deft or as spontaneous as some other professional guitarists can be. Perhaps he tried not to make too many demands on the accompaniment. The Sinfonietta also played Chabrier's Espa?a and Falla's two Three-Cornered Hat Suites. The orchestra did not score very highly in terms of fluency and often seemed too afraid to let themselves go. But occasionally there was appreciable fire and drama. The violins and brass in particular had improved, being able to produce fulsome, rounded tone.
