HAYDN: STRING QUARTETS OPP.71 & 74 The London Haydn Quartet continue their critically acclaimed series celebrating their namesake, which The Guardian raves has, "too many pleasures to enumerate." Haydn wrote his six "Apponyi" quartets in 1793 for performance during his second London visit the following year. This is a world in which the members of The London Haydn Quartet are very much at home, and they bring all their usual attentive enthusiasm to these masterpieces.
