This is a remastering of a concert given by the Gerhard Quartet at the Fundacion Juan March on 6 June 2023. It features the world premiere recordings of String Quartets Nos. 6 and 7bis by Conrado del Campo (1878-1953), one of the most original but least well-known Spanish composers of the first half of the twentieth century. The concert was part of the Proyecto Conrado, whose remit involves progamming the first complete cycle of his thirteen string quartets; producing a complete edition of the scores, most of which have never been published; and releasing recordings of the quartets (in various formats). The aim of this ambitious initiative is to rescue a significant body of of works from the undeserved neglect into which they have fallen.
