So we have Gabriela Lena Frank's six movement Leyendas: An Andean Walkabout (2001), the very familiar Lou Harrison in a fairly late work, from 1978-79, String Quartet Set, which deals in Middle-Eastern influences for the most part, Jose Evangelista's Spanish Garland: 12 Folk Melodies from Spain (1993), the Persian inspired Nayshaboorak (Calligraphy No. 6) (2005-6) by Reza Vali, and Elena Kats-Chernin's Uzbekestanian rooted Fast Blue Village 2 (2007).
The works fit together well, thanks to their emphasis on melodic characteristics and on the Del Sol Quartet's very direct, no-nonsense interpretations/performances.
It's a beautiful set, a change of pace for the modernist ear that can still welcome and appreciate new ways of making the music alive again. It is also quite a feather in Del Sol's cap. They sound marvelous.
