Steve Reich occupies a weird place in modern music. He's one of the  most-respected modern classical composers and right on the cusp of the  avant-garde, winning prestigious accolades like a Pulitzer and a Grammy.  Yet at the same time, he's something of a rock star in the classical  world. He writes pieces that successfully connect with a younger  generation of musicians, influencing artists, composers and ensembles as  diverse as Sufjan Stevens, King Crimson, Brian Eno and A Silver Mt. Zion. When Reich composes, people tend to pay attention. His newest album, WTC 9/11, compiles three of his latest compositions.
The title piece, WTC 9/11, was originally written for the Kronos Quartet in 2010. It utilizes a technique Reich used on his earlier piece Different Trains,  which was also originally performed by Kronos. He utilizes the notes in  spoken word recordings taken from NORAD and FDNY to craft the melodies,  which are played over a repetitive backing. The first movement of the  piece is by far the strongest; the intense voice clips and blaring dial  tone create the perfect, terse atmosphere of confusion and desolation  that this piece so desperately tries to convey. It strongly recalls the  uncomfortable strength of the wailing trains in movement two of Different Trains. The second movement of WTC 9/11,  however, feels much less inspired. This portion of the piece feels  almost a bit too empty, even by minimalism's standards. The voice clips  feel disconnected and awkwardly placed. While the emotional impact is  still immensely strong, as was no doubt Reich's main goal, the music  itself feels a bit too dreary, plodding along a bit more slowly than  most listeners will stand for. The third movement, however, does feel  like a fitting finale, bringing some musical relief to the emotional  turmoil Reich sought to deal with. It's an extremely effective piece on a  visceral level, but musically, it's not as strong as Reich is capable  of.
The second selection is the 2009 piece Mallet Quartet, performed by S? Percussion. The piece was originally written for soloist and tape, in much the same style as his recent works 2 x 5 and Double Sextet.  Even though this recording lacks the novelty of actually playing  against a tape, it still features the delicate rhythmic interplay that  makes Reich's double ensemble tracks so intriguing. It's narrowly the  strongest of the three selections on this album, harking back tonally to  some of Reich's mallet-heavy pieces like Music for Eighteen Musicians or Music for Mallet Instruments, Voices and Organ.
The final and oldest piece, 2002's Dance Patterns,  delves into several different short vignettes of dance melodies,  alternating between the up-tempo and the largo. The rhythms are  beautifully intricate without losing the accessibility of the melody  that makes this piece so danceable in the first place; it's easily one  of Reich's most enjoyable pieces, comparable to Vermont Counterpoint or Tehillim.
Though  the title track doesn't quite live up to the gravity it was intended to  have, this collection is nonetheless a strong and welcome entry in  Reich's already quite vast discography. It is both a wonderful  introduction to Reich's style of minimalism and a fresh listen for  veterans of the genre.
