If Steve Reich's Music for 18 Musicians is simply described in terms of its materials and organization – 11 chords followed by 11 pieces built on those chords – then it might seem utterly dry and monotonous. The actual music, though, is far from lackluster. When this recording was released in 1978, the impact on the new music scene was immediate and overwhelming. Anyone who saw potential in minimalism and had hoped for a major breakthrough piece found it here. The beauty of its pulsing added-note harmonies and the sustained power and precision of the performance were the music's salient features; and instead of the sterile, electronic sound usually associated with minimalism, the music's warm resonance was a welcome change. Yet repeated listening brought out a subtle and important shift in Reich's conception: the patterns were no longer static repetitions moving in and out of phase with each other, but were now flexible units that grew organically and changed incrementally over the course of the work.

Alarm Will Sound's recording of Steve Reich's monumental orchestral/choral works The Desert Music and Tehillim, released on the Cantaloupe label in 2002, greatly benefits from the group's close connections with the composer: the ensemble's conductor, Alan Pierson, and several of the performers studied at the Eastman School with Brad Lubman, a conductor frequently enlisted by Reich. Also, Pierson's arrangements, which reconcile the chamber and orchestral versions that exist for both works, were prepared in close consultation with the composer; thus, this may well be the definitive recording of these pieces. Brilliantly sonorous in their climaxes – the burst of light near the end of Desert Music, the "Alleluias" that close Tehillim – the players also articulate Reich's intricate canonic textures with nimble precision.

For all the agony as to the status of classical music in the modern musical landscape, the three 20th century string quartets on this fine French release can be said to have entered the repertory, with a reach that extends far beyond the U.S. They go quite well together, which is the first point in favor of France's Quatuor Diotima here; both Steve Reich's Different Trains, for string quartet and tape, and George Crumb's Black Angels for electric quartet feature an artificially enhanced string quartet, and even Samuel Barber elected to "enhance" his String Quartet in B minor, Op. 11, by orchestrating its central movement and making it into the famous Adagio for strings. Highly recommended.

The SWR Vokalensemble Stuttgart is one of the few choirs enjoying an international reputation. Their latest recording has “America” as its subject - and presents a tremendously wide range of forms and expressions, from music written under the influence of European masters to works that boldly explore experiments in aesthetic reorientation. The big names of the U.S. composers are of course represented, including Leonard Bernstein with his single a cappella work, the “Missa Brevis”, Steve Reich with his minimalist “Proverb” and John Cage with some of his late “Number Pieces”. Everything is presented at the highest artistic level, with ravishing sonics that cannot be beat.

A collection of musical gems by great contemporary composers of the minimalist and postminimalist trend. Music of Steve Reich (Vermont Counterpoint, New York Counterpoint - first recording of the saxophone version), Arvo Pärt (Pari Intervallo), Hans Otte (Eins), Ludovico Einaudi (Quattro Passi), Henryk Mikołaj Górecki (For you Ann Lill, Op.58), skilfully interpreted by Andrea Ceccomori and Goffredo Degli Esposti on the flutes, Paul Wehage on the saxophones, Cecilia Chailly on harp and Fabrizio Ottaviucci on piano.

There’s something special about this version of Different Trains. It’s the one commissioned by Wolfgang Sawallisch and David Robertson and their respective orchestras (Philadelphia and Lyon) in 2001 for string orchestra, and it impresses immediately by the richness of its vastly expanded sound palette. Though it may be heresy to say so, I never found the original string quartet version entirely convincing. This recording shows why: inside that frenetic chamber work was a much larger piece trying to get out, and here it is, fully realised, as it were, in glorious technicolor.

This collection of music for guitar, brought together by Jose Luis Bieito as the musical element of his music+image binomis, Reflections, possesses a delightful balance of sounds. These are flowing, pulsing, mostly gentle sounds that tend to soothe and calm the listener's mind. Sounds that - through a variety of compositional techniques - tend to be sustained in time; the effects of which can sometimes capture a listener’s attention, holding it inside an extended musical moment, like a spell. When heard while viewing the accompanying (provocative, sometimes disturbing) images, the sounds can serve an additional function: grounding the listener's reaction, enabling the passage of emotion; like electricity discharging through a lightening rod.

As more ensembles perform and record Steve Reich's Music for 18 Musicians, its status as a minimalist masterpiece is increasingly affirmed. Ensemble Signal's 2015 release on Harmonia Mundi is one of several amazing performances that have matched Reich's original ECM New Series recording in technical brilliance and expressivity, and it has even earned the composer's approval for being, "…fast moving, spot on, and emotionally charged." Under the direction of Brad Lubman, Ensemble Signal maintains a relentlessly steady pulse and articulates the interlocking patterns with absolute precision, though the shifting tone colors are perhaps a little clearer in this performance than in other recordings. The microphone placement is not so close that individual instruments stand out, but there is enough separation of parts to allow some sense of direction and the orientation of the smaller sub-groups of pianos, xylophones, marimbas, strings, clarinets, and voices. This is a mesmerizing performance that will transfix listeners, and the music is so compelling that it will linger on well after the CD stops. Highly recommended.
