The album showcases some eight works from this past century, not precisely doctrinaire Nationalistic but not not either--in other words there are strong folkloric-folk elements as well as local pop influences. a shade of Later Romanticism but then a marked descriptive quality, with attention to orchestration and expressivity that may recall a little Stravinsky or Villa-Lobos, maybe a hint of Chavez. not exactly going out of the way to build an overt Modernism but then unmistakably of the last century (or the very end of the century before) once you listen closely.
The names might not be familiar to you (they were not for me, mostly) but each has something to contribute on this illuminating anthology--Alejandro Tobar in a 1967 work, Alfonso Leng in one from 1912, Alberto Williams, 1889, Jose Carlos Campos, 1981, Santos Cifuentes, 1894, Celso Garrido-Lecca, 1983, Enrique Soro, 1916, and Francisco Pulgar Vidal, 1989.
There is simply too much music to try and describe each. They taken altogether give us a rather varied but interrelated draught of Peruvian expression. It may not upset the apple-cart of contemporary music, but it is thoroughly enjoyable regardless. I recommend it for those willing to consider some interesting orchestral music we might otherwise not get a chance to hear. Listen!
