One listen to Lisa Gerrard's The Silver Tree (originally available only digitally, then as an Australia-only import, and finally, as a U.S. release) is enough to convince anybody – who isn't already convinced – that there's a very specific reason she has been courted by directors to compose soundtracks. There are 13 tracks here full of wispy ambient soundscapes, on top of which the former Dead Can Dance vocalist places her almost otherworldly gift of a voice. Sung nearly as prayers or meditative mantras, Gerrard employs monosyllabic glimpses of other languages – and occasionally English – to create her own tapestry of dreams. Some may be tempted to call this "new age" music, but it's so much more melancholy than much of what passes for that trash, and it's nearly sacred in its approach to articulation, creating the feeling in places ("Come Tenderness," "The Sea Whisperer," and "Abwoon," to name a few) that she is actually singing inside a cathedral. In other places, such as "Wandering Star" and "Serenity," her voice offers a drone approach that is as subtle – yet powerful – as her instrumentation.

Immortal Memory is a collaboration between vocalist Lisa Gerrard and Irish composer Patrick Cassidy. Billed as a cycle of life and death and rebirth, Immortal Memory is better described as an orphaned film score. Cassidy's warm arrangements allow the former Dead Can Dance singer to step out of the dark medieval world that she's called home for nearly 20 years – though there is much of that world within these castle walls – and focus on the simplicity of love, faith, and loss with a grace that's bereft of the icy perfection of her previous work. Gerrard, whose voice has aged like the finest oak, displays an almost supernatural mastery of the material. Her effortless contralto wraps itself around the ten Gaelic, Latin, and Aramaic spirituals like an evening prayer, making each stunning entrance the equivalent of audio comfort food.

Ryuichi Sakamoto, one of the pioneering figures of Japanese electronic music, demonstrates his versatility on this change-of-pace album. Released in 2004, 04 is dominated by Sakamoto's prowess on the acoustic piano, and features excerpts from several of his scores for motion pictures (including his music for Merry Christmas, Mr. Lawrence), television commercials (such as a campaign for Louis Vuitton), and video games ("Seven Samurai: Ending Theme" was composed for the PS2 game Seven Samurai 20XX).

An incredible batch of Brazilian fusion – cut by keyboardist Manfredo Fest, and one of the few records he ever waxed in the US during the 70s! The record mixes Fest's soaring Brazilian groove with a tight soulful set of arrangements by Jerry Peters – a bit club-oriented, with a similar sound to some of the other records on the Tabu label at the time, but always sensitive to Fest's playing and writing – especially his Brazilian roots! The record features wonderful vocals by Roberta Davis – a very soulful singer who had a hip wordless style that was similar to Tania Maria's at the time – breezy, scatting, and very nice. Her work really makes the record sparkle, working perfectly with Fest's jazzy electric keyboards in a perfect way!

As Il Sospiro shows, Rabih Abou-Khalil's music is unique, in that it spans East and West - or rather the Middle-East and Europe - in a way other composers have attempted, but with much greater success. Raised in the cosmopolitan climate of pre-civil war Lebanon, and privileged to learn the oud there, he was forced to migrate to Munich where he studied classical flute. His rediscovery of oriental music from a European vantage point has both freshness and also the familiarity of long acquaintance. His best disc to date has been Yara, a film soundtrack for which he teamed his oud with a violin and cello plus the Middle Eastern frame drum, to create a haunting sequence of visually evocative pieces. With Il Sospiro he makes his first solo foray as an unaccompanied oud player, and the result is even more bewitching…

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.

Issued in 2007 on the 4AD label, THE BEST OF LISA GERRARD collects many of the finest tracks by the former Dead Can Dance vocalist/multi-instrumentalist. While the compilation includes a few tracks by that revered act, most notably the mystical "Yulunga (Spirit Dance)," a song that showcases Gerrard's striking voice, it primarily focuses on her solo work and film compositions, which both draw from music across the globe. On these pieces, Gerrard often collaborates with fellow Australian native Pieter Bourke, as on the passionate "Swans" and the expansive "Sacrifice," the latter from the INSIDER score. Although this anthology is a mere fraction of Gerrard's recorded output, it does serve as an excellent introduction to her impressive catalogue.

Erik Truffaz received an early introduction into the world of a professional musician, thanks to his saxophone-playing dad. When he was ten years old, the French trumpeter began performing in his father's dance band. As he grew older, Truffaz performed with other bands in the region until he was 16 and heard Kind of Blue by Miles Davis. The great jazz trumpeter's music inspired him to learn more, and he set off for Switzerland's Geneva Conservatoire, where he became a student. Truffaz's repertoire expanded to works by Mozart and Verdi, and he performed as part of L'Orchestre de Suisse Romande. He also played in cover bands before establishing a group called Orange. The band concentrated on Truffaz's compositions…

Hector Zazou invites four outstanding instrumentalists from India and Uzbekistan to step into a virtual hall of mirrors, in which sound is reflected from one note to another: an aural equivalent of a famous scene in Orson Welles' The Lady From Shanghai.
Twenty-five years after laying the foundations for Afro-electronic fusion (with Congolese singer Bony Bikaye on the “Noir & Blanc” LP), and after many other groundbreaking albums, the ever-innovative Hector Zazou offers a fresh take on classical Asian music, in which the musicians' inspired performances are enhanced by his subtle reprocessing of the original sonic elements (no supplementary electronic sounds having been used)…

Recorded in Germany by Beirut native Rabih Abou-Khalil, this moody, atmospheric album is more like a soundscape than a collection of songs. Abou-Khalil's primary instrument is the oud, a lute-like instrument traditionally used in Arab music. This low, sweet-toned, obviously Far Eastern instrument is teamed up with nothing more than Arab drums in most of the songs. Sparse vocals, performed by Selim Kusur, do little to create any discernible melody. Instead, they add texture and effect - or an intro in the case of "Incantation." Upbeat songs such as "Awakening" are carried along by the drums, while the melancholy sound of the oud dominates introspective tracks such as "Nafas." This album is a far cry from the complex, percussion-heavy, often slightly jangly albums that usually make it to the world music section in Western record stores…

Cassandra Wilson continues to move down a highly eclectic path on Belly of the Sun, the somewhat belated follow-up to Traveling Miles. While displaying a jazz singer's mastery of melodic nuance and improvisatory phrasing, Wilson draws on a variety of non-jazz idioms – roots music, rock, Delta blues, country, soul – to create a kind of earthy, intelligent pop with obvious crossover appeal. Her core band includes guitarists Marvin Sewell and Kevin Breit, who blend marvelously, Sewell mostly on mellow acoustic and Breit adding atmospheric touches on electric, 12-string, and slide guitars, as well as mandolin, banjo, and even bouzouki.
