Review: Motor City great Omar S is not just a don when it comes to programming drums and laying down his irresistible synth lines and heart aching melodies. He can also play a wide array of instruments, and in fact does just that here as he plays all instruments played you can hear across all three cuts of this new one on his FXHE label. Things kick off with the wonderful 'Featuring Omar S (instrumental)' and then 'Sayoungaty Nig' is a hazy, lo-fi ambient sound with occasional synth smears and a barely-there rhythm implied by the odd kick drum sound. 'Featuring Omar S' is a signature deep house joint with bristling metal hi-hats, rickety drums and edgy drones that keep you on edge as more soulful chords rise up through the mix.

Review: With a title inspired by the utterances of The Oracle of Delphi, a cult of female priestesses who reportedly "changed the course of civilisation" by inhaling volcanic vapours, it's clear that Lee Burtucci and Olivia Block's first collaborative album is rooted in paganistic visions and experimental mysticism. It's comprised of two lengthy tracks, each accompanied by edited 'excerpts', and combines Burtucci's experimental synth sounds and tape loops with Block's processed vocalisations and hazy field recordings. Dark and suspenseful, with each extended composition delivering a mixture of mind-mangling electronics, creepy ambience and musical elements doused in trippy effects, it sits somewhere between the charred "illbient" of DJ Spooky and the deep space soundscapes of the late Pete Namlook.

Review: In the right circles,, Martin O'Donnell and Michael Savatori are living legends. Working with the iconic US video game company Bungie Inc, the pair put their names on the map - or maybe maps? - by creating soundtracks to a number of high profile titles, either as a duo or individually. O'Donnell is arguably the better known, or at least has the bigger online persona, but both composers deserve plenty of credit. Halo: Combat Evolved was the first title in what is now a huge and genre-defining first person shooter franchise, and the score reflects the emergence of video game music as an integral part of the on-screen action. O'Donnell and Savatori's efforts to ensure instrumentation dramatically changed with events in the game, which is by nature relatively non-linear, was a revelation. While their efforts to separate these into individual suites foresaw the rise of playable stories as films in their own right.

Review: It's been a long time since Halo: Combat Evolved revolutionised the word of first-person shooter video games. Graphically superior to anything that had come before it, the franchise also benefits from a spectacularly gripping storyline in which humans are outgunned and out-teched by a ruthless and uncompromising alliance of superiorly equipped alien races united as The Covenant. The titular Halo adds a kind of Prometheus air of uncertainty, as nobody really knows what it does until attempts to activate the galaxy-destroying weapon reveal something worse than death - a parasitic breed called the Flood. If all that was enough to blow everyone away in 2001, 2004 brought us to a whole new level of immersion in this future scape. Just like its predecessor, a big part of the impact was the visionary score by gaming soundtrack masters Martin O'Donnell and Michael Savatori. Now here it is in all its Gregorian chanting glory.

Review: Laced Records and Halo Studios partner up to bring the epic soundtracks of the original Halo trilogy to vinyl for the first time, remastering and revamping 83 original scores from Halo: Combat Evolved, Halo 2, and Halo 3. the music that defined a franchise is thus ethered in perpetuity. Weaving orchestral elements, prog rock, drum corps marches, and heavy metal, Halo presents a perfect bottling of angst and militancy; owing to its popularity with a certain teen gamer cohort, Halo 2's score especially made history as the first video game OST to chart on the Billboard 200. Now, each soundtrack is presented in its own sleeve with custom artwork, and comes in a collector's box adorned with a debossed Halo logo and silver laminate finish.

Review: Calling the curtain on Field Records' Waterworks trilogy, Yui Onodera turns his ear to confluences of hydrology and history, dedicating his latest record to Japan's Kiso Three Rivers and their transformation by 19th-century Dutch engineering. The Kiso, Nagara and Ibi rivers, once prone to catastrophic flooding, were reshaped under the guidance of Johannes de Rijke, whose work helped protect Nagoya from seasonal deluge by 1912. Onodera, known for his nuanced sound architecture, approaches this subject with a finely honed ear for subtlety, layering quiet field recordings with fuller instrumentation, evoking the widening of a river from brook to strait. The A-side's bell tones provide a sensory-meridian intimacy, processed alongside guitar, and ethereal pads; while the B-side's contradictorily colossal quietude makes itself across two long-form studies, which drift through sampled water and restrained electronics.

Review: We Carry Eden is an album so deep you can plunge right into it and forget the real world entirely. It comes from Son Of Chi, the latest project by Dutch ambient pioneer Hanyo van Oosterom, and it melds drones, field recordings, dub, jazz and fourth world influences across a two-part composition that features storytelling by West African vocalist Omar Ka. A founding member of CHI and Chi Factory, van Oosterom crafts textured soundscapes rooted in meditative grooves and spiritual depth and is inspired by Patmos and Hopi wisdom. He also weaves nature, myth and memory into a unified sonic journey with fine artwork by Michael Willis underlining the message of harmony.
