A quick report on this. They played:
Turina - La Oración del Torero
Brower - Cuban Landscape with Rain; Toccata
de Falla - El Amor Brujo (complete suite)
de Falla - El Sombrero de tres picos (Neighbour's, corregidor's and miller's dances)
Domeniconi - Oyun
Bizet - Carmen Suite
encore: Brahms - Hungarian Dance No.5
The Bizet used Kanengiser's arrangement, the de Falla and Turina their own. The Brouwer and Domeniconi are composed for guitar quartet
In the first half their individual technical skill and ensemble playing were excellent. The Turina and much of El Amor Brujo lack attractive melodies, and though Brouwer's Cuban Landscape has rather more pleasant rain than an English audience is used to, it has a particularly unpleasant storm looking back to the composer's avant garde period. The second half received a deservedly enthusiastic reception. Superb playing of wonderful music.
They plan a CD for later in the year (which I look forward to with eager anticipation). I don't know if they have any more performances planned, but recommend hearing them if you get the chance.
