Roger Reynolds (1934- ) turns 90 next year. This prolific American artist’s work is being collected and preserved by the Library of Congress. The present recording is the most recent release documenting Reynolds’ music, now numbering about 30 CDs and DVDs. And this is but a fraction of his musical works.

I first encountered Reynolds’ music when I heard a broadcast of the first commercial recording of his music. The disc, released in 1969 on Nonesuch records documented performances of Frederic Myrow’s “Songs from the Japanese” (1964) paired with Reynolds’ “Quick are the Mouths of the Earth” (1965), a work that actually uses the text of the title to derive the music. I recall that the sound of this music sent chills up my spine and sent me to a record store to purchase a copy. This first encounter was a visceral experience, one of many I would encounter as I heard his subsequent music, and that of his contemporaries.

Reynolds has been a prolific composer, writer, and reader. His father was an architect, Roger would go on initially to study engineering and then also encountered some of the new interest in experimental music at the ONCE Festival in Ann Arbor, Michigan in the early 60s. His studies in music and literature continued to be wide ranging and the fine liner notes by Thomas May in “For a Reason” are extremely useful in grasping the range of inspirations that inform Reynolds’ music. This is one of those gorgeous new music releases that will likely become one of those odd but much sought after collectibles. The booklet jdesign by Karen Reynolds, Stacie Birky Greene, and producer Philip Blackburn is by itself, worth the price of this release.

While listeners can certainly appreciate Reynolds’ work without those details, they add a dimension of understanding and provide contexts as well. In some ways, Reynolds is unclassifiable but this writer finds him to be the consummate experimentalist and modernist, two aspects that appear to have been in his work from the very beginning. His work is rarely easy listening but, even if you don’t get it on first hearing, his compositions tend to reveal weight and substance with repeated listenings.

That said, Reynolds’ music produces sounds that might be heard as romantic, expressionist, and even classical at times. Much of his work, as is the case with most of this 2 CD set, is electroacoustic. It is not heavily dissonant or overly complex to the listener’s ear but his music presents unique challenges to performers. And, as mentioned, this beautifully designed set includes a decent set of liner notes to help navigate this voyage.

Three of the four works here are “electroacoustic”, meaning that some form of electronics interacts with the performer. The one work that does not fit that category pretty much needs it’s own category. Pieces for speaking pianist are getting more common in the last 20 years or so but pieces for speaking percussionist are far less common. Frederic Rzewski’s “To the Earth” for speaking percussionist playing on clay flower pots comes to mind. Of course John Cage also wrote in this genre but Reynolds’ essay is the longest, most complex work this listener has encountered for solo percussionist with speaking duties.

The first track is “Dream Mirror” (2010), the first of Reynolds’ “Sharespace” series of compositions in which an instrumental performer interacts in the shared performance space with a computer musician in a duet. This first sharespace work is for guitar and computer musician. It features the fine Mexican guitarist, Pablo Gomez Cano. The fact that Cano is not a familiar name is likely that his work has focused on challenging new music such as this. Dream Mirror is a big work, at over 20 minutes in performance, but it has a chamber music quality consistent with the composer’s focus on the interaction of this duet in their shared performance space.

The second track introduces listeners to the fourth in the Sharespace series, this time, for violin. “Shifting/Drifting” (2015) was written for Irvine Arditti, one of the finest working musicians of our time supporting new music via his solo efforts and his work with his esteemed “Arditti Quartet”. Like the preceding track, this big duet takes some 20+ minutes in performance.

On to CD 2 for the third offering, “Here and There” (2018), both the longest work and the most recent. This one is for solo percussionist with a substantial speaking part designed to be spoken by the percussionist (in this case, Steven Schick, one of Reynolds’ fellow faculty at UCSD). Solo percussion works are relatively uncommon, though readers will want to familiarize themselves with volume one of Mr. Schick’s ongoing series of the solo percussion repertoire Hard Rain.

This will likely become a showpiece but, at the time of this writing only Schick and the ubiquitous William Winant come to mind as being both willing and able to perform this work right now. And it is apparently a beast of a challenge for the performer but remarkably engaging for the listener. The texts, from Samuel Beckett, are referenced in the liner notes. Not surprisingly, Schick delivers a stunning performance, setting a bar for successive performers and performances. The texts are non-narrative and have a more musical than didactic or dramatic function.

Last but not least is the earliest work on the album, “Sketchbook”(1985), originally written for Joan LaBarbara but never performed. Here, singer, Liz Pearse effectively took a page from Irvine Arditti (whose doctoral studies resulted in research that culminated in John Cage being able to finish his partially completed solo violin work, “Freeman Etudes”). Pearse, also pursuing doctoral studies came upon this work and collaborated with Reynolds in creating a performance. His texts here come from Milan Kundera. The work, while dramatic and challenging, is not a species of opera or monodrama but, like the preceding works, a piece that, like Reynolds, thrives on collaboration. In addition to requiring some pianistic skills, the singer collaborates with interactive computer electronics.

These four works, despite their differences, clearly fit Reynolds’ interest in literature, collaboration, and in various technical aspects described in the well documented liner notes. Those notes provide technical detail and insights beyond the scope of your humble reviewer’s skills but what I can tell you is that this release is a marvelously engaging experience revealing fascinating aspects of this composer’s work.

The experience of listening and reading and the visual experience of the graphics was an immersive one and a delightful use of my time. Heads up to all my fellow new music aficionados. This is truly spectacular.
