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: 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: 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: 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: For the first time on vinyl, through Karl Records, comes a limited edition and furtive Yoko Ono retrospective, in conjunction with the over-100-strong, Sweden-headquartered ensemble and community network The Great Learning Orchestra. These unlikely recordings were made at the time of the musician and performance artist Ono's 1964 multimedia collection Grapefruit, a cornerstone of what would later become known as "conceptual art". Grapefruit itself is a large artist's book, with a large vellum spine and browned parchment paper; it contains a series of "event scores" that outline, rather than permit the performances of, many different performance art pieces. The effect is apocryphal and ominous, as though the real performance of these instructive works may have accursed or deleterious effects. "Like a musical score, Event Scores can be realized by artists other than the original creator and are open to variation and interpretation"; and yet, Ono's book is a one of one, having never been reproduced or thus made collectable. Pre-dating John Cage by about a decade, the "event scores" described therein have now been performed by The Great Learning Orchestra, where hardly any of the performances / pieces have ever been captured sonically or laid to disc. This record changes all that, realising Ono's bewildering text instructions as tremulous suites, made up of clattering material hits and harrowing string instrumental assaults.
