Orquesta Sinfónica de San Luis Potosí / José Miramontes Zapata JULIÁN CARRILLO

This extraordinary musician was born in the village of Ahualulco, San Luís Potosí, on January 28, 1875, the same year as Ravel, Melartin, Gliere and Max d’Ollone. He began his formal studies at the age of ten in the State Capital and later moved to Mexico City to continue his education in the National Conservatoire (Conservatorio Nacional de Música).
In 1899 the Mexican government awarded a grant to the young musician, then aged 24, to continue his studies in Europe. In Leipzig he entered the Royal Conservatoire where he studied composition with Salomon Jadassohn, violin with Hans Becker and theory with Carl Reinecke, who also taught another great Mexican composer: Ricardo Castro.
The San Luis Potosí Symphony Orchestra achieved great renown in the international perspective under José Miramontes Zapata’s direction. The orchestra has been invited to important events such as the 2003 and 2005 Festival Internazionale della Associazione Mondiale Toscanini, to the Ravello Festival in 2005, both in ItJulián aly, and to the 2005 Musicalta Festival in Alsace, France. That same year, the San Luis Potosí Orchestra became the first Latin American Orchestra to perform at the Grosser Musikvereinssaal in Vienna, Austria, under the direction of José Miramontes Zapata, who became the first Mexican conductor to perform at Vienna’s Great Hall, one of the leading concert halls worldwide.

American Festival of Microtonal Music Ensemble CARRILLO - PARTCH - IVES - SCELSI - XENAKIS - HARRISON Chamber

Want to stretch your ears? This disc is one of the best introductions to the world of microtonal music. The program consists of six works, each with its own approach to defining and using tones outside standard notation and keyboard configuration. To many listeners some of these pieces will seem simply out of tune, but others will find them merely strange-sounding. Just a touch of music theory to explain things: You can get microtones by slicing the equal half-step intervals of a piano scale into narrower equal fractions. Since the equal half-steps are really a slightly-out-of tune compromise to accommodate our modern system of equal temperament, such "quarter-tone music" exaggerates the out-of-tuneness but creates remarkably tangy harmonies.
This is best illustrated here by Julian Carrillo's Prelude to Columbus, a work for voice, flute, guitar, harp, and string quartet. Carrillo, one of the true pioneers of this kind of music, uses quarter-tone (and narrower) intervals both as ultra-expressive passing tones and to create fresh, dark harmonies.
Another approach to enlarging the palette of notes is to refuse to accept the compromise of equal half-steps and instead use scales whose notes coincide with "natural" overtones. Harry Partch was the pioneer of this approach and is represented by his Finnegan's Wake songs. Soprano Meredith Bordon is the able soloist in both Partch's and Carrillo's compositions. Her recital-style voice is accurate and strong. Lou Harrison, a follower of both Partch and Charles Ives, contributes a typically attractive Tombeau for Ives, using his own adaptation of Partch's ideas.
But the stand-out performance on the disc is Ives' own Second String Quartet. Harmony Ives once instructed a copyist not to "correct the spelling" of her husband's scores. (For instance, not to turn an E-flat into D-sharp, for these notes, identical pitches in standard notation, are different pitches in a "natural overtone" scale.) She went on to explain how Charles perceived the relationship of such putatively identical notes. AFMM leader Johnny Reinhard realized that she was describing a natural-overtone scale system of 21 notes, and this is billed as the first recording to play this great string quartet in this manner. A valuable alternative to great standard readings, this performance reveals a softer, dreamier, less satiric affect.
The music discussed so far is all tonal. In Anaktoria, Iannis Xenakis writes atonal music, so all the notes are equally valid and nothing sounds out of key; that is to say it is consistently dissonant. Xenakis' sound is bold, generally harsh, without melody or traditional rhythm, but conveys a sense of power and monumentality that is exhilarating (assuming it doesn't send you running for the door instead of listening!). This is an excellent performance, aided by the precise intonation of the experienced AFMM players. Along with the Ives, Anaktoria is a primary reason for my strong recommendation to daring listeners. Giacinto Scelsi's eight-minute piece also is atonal and uses micro-steps--but like most of Scelsi's work it fails to reveal anything of real musical value. Obviously producing a labor of love, Reinhard and his musicians give exciting, committed readings. Sound is slightly studio-bound, but clean. In sum: The disc is well worth acquiring, even if you decide to skip Scelsi on subsequent playings. (Joseph Stevenson, ClassicsToday.com)
