Naxos’ exciting and important American Classics series now includes music of the present day, in this case three recent works by Philip Glass. The Violin Concerto, a work that (surprisingly) adheres to classical conventions, lures us in with beautiful, seductive harmonies. Glass relies both on his trademark arpeggiated technique (sounding in the first movement somewhat like Vivaldi’s “Winter” concerto) and on his favorite harmonic progressions to suggest a sustained melodic line. In the first two movements Glass’ carefully timed harmonic and rhythmic shifts keep you in a happy daze. He breaks the mood in the finale, however, leaving the soloist to practice arpeggios at length until the quiet, serene coda steals in. Adele Anthony, who plays with the kind of skill and grace we would expect in a Mozart concerto, brings off Glass’ work with consummate, convincing musicianship. Company (music for Becket’s prose) for string orchestra is in four movements, characterized by stimulating changes in time signature and rhythm.

Initially conceived as a moral and artistic response to human suffering, violinist Edna Michell's Compassion also became a touching tribute to her mentor and source of inspiration, Yehudi Menuhin, on his death in 1999. The 15 compositions commissioned by Michell for the project revolve around the themes of suffering and charity in fairly abstract or suggestive ways, with few programmatic, religious, or political points made beyond the allusive titles. As a practical matter for curious listeners, this CD is a comprehensive sampler of contemporary musical trends, and the leading lights of two generations of composers are generously represented in the CD's 80 minutes. Established figures such as Karel Husa, Lukas Foss, György Kurtág, Hans Werner Henze, Wolfgang Rihm, Philip Glass, John Tavener, Steve Reich, and Iannis Xenakis share the program with rising composers Shulamit Ran, Chen Yi, Yinam Leef, Betty Olivero, Poul Ruders, and Somei Satoh.

The New Seasons referred to in the title here are the so-called American Four Seasons, the Violin Concerto No. 2 of Philip Glass, which has even less of a connection to Vivaldi's model than do Astor Piazzolla's Buenos Aires Four Seasons and other works that take Vivaldi as a point of reference. The work is in eight sections, but which ones are supposed to represent which season is left up to the listener. It's really a typical but unusually effective example of late-period Glass, with the composer's usual textures intact but lots of harmonic motion. Part of the interest here lies in hearing Latvian violinist and conductor Gidon Kremer and his Kremerata Baltica, long champions of minimalism's Baltic branch, tackle a work by one of the leaders of Western minimalism. The American Four Seasons get a treatment that's a bit rougher than usual, but then Kremer turns around (after a Pärt girls' choir interlude) and delivers pristinely smooth, glassy textures in Giya Kancheli's Ex contrario. The program closes with a fascinating little melody by Japanese rock musician and film composer Shigeru Umebayashi, a daring and effective choice.

An album the majority of whose contents consists of harp arrangements of music by Philip Glass might seem a bit arcane for a major label, but it seems that Sony knows what it is doing here. The Glass Effect double album is one of those releases that succeed on two different levels, an explicit one and one that, although not mentioned, is perhaps even more important. The former level here is the one denoted by the title, as Meijer picks up the rather neglected theme of Philip Glass' influence by offering, on disc two, a group of works by younger composers who follow Glass in varying degrees but who, it's safe to say, wouldn't have the styles they do without Glass having gone before. Much of the album consists of arrangements by Meijer herself, and these include, at the end, a remix of music from Koyaanisqatsi that's delightful and would be spoiled by description. But there's also solo harp music: sample the Suite for Harp by progressive rock musician Bryce Dessner, who certainly seems to have absorbed Glass' style far enough to make it his own.

Philip Glass' soundtrack to Martin Scorsese's Dalai Lama epic Kundun captures the grace, beauty, joy and melancholy within the film. Glass uses familiar minimalist structures, but works with traditional Tibetan instrumentation and monks, giving the music an alluringly otherworldly feel. It's an entirely original, evocative score, and one of Glass' high-water marks in the field.

The piano may not be the ideal medium for capturing the expressive possibilities of Glass' style of minimalism, but pianist Bruce Brubaker selects pieces that work well on the instrument. Part of the problem with hearing Glass on the piano is forgetting the sound of his ensemble, and the variety of colors (and volume) they have imparted to similar music. Brubaker begins his recital of works by Glass and Alvin Curran with his transcription of "Knee Play 4" from Einstein on the Beach. It is in fact a lovely piece on the piano if one can put the spectacular power and tonal range of the instrumental version out of one's mind. "Opening" from Glassworks, originally scored for piano, works beautifully on the instrument, and flows as naturally as the C major Prelude from Book I of The Well Tempered Clavier. The two pieces by Curran, Hope Street Tunnel Blues III and Inner Cities II, use a syntax similar to Glass, with a more dissonant tonal vocabulary. Hope Street Tunnel Blues III has ample kinetic energy that gives it an exhilarating momentum.
