This is a remastering of a concert given by the Quatuor Diotima at the Fundación Juan March on 27 April 2022. It features the world premiere recordings of String Quartets Nos. 3 and 5 (six-movement version) 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, which involves programming the first complete cycle of his thirteen string quartets. This will go hand in hand with the publication of a complete edition of the scores, most of which have never been published, and the release of recordings of the quartets (in various formats). The aim of this ambitious initiative is to rescue a significant body of works from the undeserved neglect into which it has fallen. ATTENTION: please remember that all Blu-Rays are Region A USA and all DVDs Region 1 USA and you will need a multi region Blu-Ray/DVD player to play them.
