Having listened to this wonderful playing, I would love to hear other tremolo guitar pieces in piano arrangements. Barrios's Una Limosna por el amo de Dios could sound very effective, or Campanas del Alba by Sainz de la Maza. Can we think of any others?
Re. the original question, The Villa Lobos Preludes which I heard Joanna McGregor play in a recorded concert, seemed a worthwhile project. She played No1 & at least one other.
