Upgrading an earlier two-fer CD that curiously omitted great swathes of both albums, the coupling of 1979's breakthrough Replicas and the 1978 demos that comprised The Plan is both chronologically and musically askance – one entire LP, Tubeway Army's eponymous debut, divided these two projects in time, and while it, too, barely hinted at the utter re-evaluation that Gary Numan would soon be making, the jolt would have been a lot less pronounced had some kind of internal logic been adhered to. No complaints, of course, about the bang for your buck. No less than 38 tracks are spread across the two discs, as the original 12-track The Plan and ten-song Replicas are joined by a wealth of bonus tracks, each offering up a full snapshot of Numan's activities at those particular points in time. The Plan adds three more of the demos that were recorded with the original LP's worth, then adds on the six songs recorded during sessions for the band's first two singles, on either side of the main attraction; Replicas is appended by half a dozen session outtakes, two of which were period B-sides.

Few bands have come to single-handedly rule a genre as well as Stereolab. The only question remaining is which genre. The band's machine-funky grooves, oddball synthetic washes, and disturbingly flat vocals suggest a futuristic disco where the survivors of nuclear war have settled for alienation anthems that recall the "space-age bachelor pad" music of the distant innocent past. But this is all conjecture. No one knows what the music of the future will sound like. (Heck, we once thought by the year 2000 we'd all be walking around in Lost in Space outfits.) Stereolab, however, are certainly what we think of.

On his 2013 release The North Borders, British producer Simon Green (aka Bonobo) continues along the organic-meets-electronic path that his 2010 release Black Sands followed, but this walk takes place as it's turning to dusk, and there are varying degrees of mist and chilliness along the way. Opener "First Fires" with Grey Reverend (singer/songwriter L.D. Brown) sounds like it could be quite warm, but it's entirely autumn-minded sweater music that wistfully wonders what to do with "faded dreams" as Green allows bits of glitchy sunlight to shine through his cloudy synth construction. "Emkay" is the clangs and echoes of a seaside port at night that wonderfully shuffles its way up to a lighthouse tune, then there's majestic songstress Erykah Badu wonderfully vibing ("We don't need no truth/Got plenty/Now it grows on trees") on "Heaven for the Sinner" over Bonobo's deep version of the broken beat. "Towers" suggests sleepy urban buildings in twilight with a vibraphone representing the little bits of life and light that will sparkle through the night, while "Don't Wait" is just before the dawn, as innocent chimes chase away the eerie things that lurk in the darkness.

Sweet Revenge is an amazingly sophisticated album in which Sakamoto sets the distinctive and heart-rending chordal and harmonic ideas of his soundtrack work to trip-hop and neo-bossa-nova beats. The songs are fronted by a succession of guest vocalists who each contribute lyrics which add up to an amazingly coherent whole–a mature meditation on love, longing, conflict, revenge and regret. As usual, Sakamoto was ahead of his time. By spotlighting the deep poetry of J-ME and Latasha Natasha Diggs, this 1994 album anticipated by years the introspective hip-hop diva trend popularized by Lauryn Hill.

Professor Sakamoto gives a lesson on what is practically a different style of music with each track on Illustrated Musical Encyclopedia, beginning with a sure-fire hit: the extroverted, quintessentially Japanese synth workout "Field Work" (with Thomas Dolby). From there, Sakamoto hits riff-ready crossover jazz-fusion ("Etude"), electronic minimalism ("M.A.Y. in the Backyard"), and Oriental dub ("Paradise Lost"). There is a return to sampladelic Eastern synth-pop with "Steppin' Into Asia," but for the most part Sakamoto displays his impressive stylistic range on this solo album.

The most amazing thing about Stereolab's Margerine Eclipse is how much of a surprise it is. It's not just that it's a fantastic record–Stereolab have made plenty of those. But since 1996's classic Emperor Tomato Ketchup, they've been deconstructing and breaking down their mix of exotic lounge pop and progressive Krautrock, throwing up cyclones of electronic mist. It's yielded some beautiful, but cold and distancing work. Eclipse shocks you with the contrast. Filled with the warmest possible intentions, it invites you to fall in love with its kind thumps and aural flotsam. Anchored by a test pattern baseline and a sly beat machine, the title track wanders around the edges, breaking into the main groove only to smoothly dissolve in a bittersweet end. Sounds like any other Stereolab song, right? But here–stripped down, dynamic, and alive–it's simply charming.

The last great Kraftwerk album, Computer World (Computerwelt) captured the band right at the moment when its pioneering approach fully broke through in popular music, thanks to the rise of synth pop, hip-hop, and electro. As Arthur Baker sampled "Trans-Europe Express" for "Planet Rock" and disciples like Depeche Mode, OMD, and Gary Numan scored major hits, Computer World demonstrated that the old masters still had some last tricks up their collective sleeves. Compared to earlier albums, it fell readily in line with The Man-Machine, eschewing side-long efforts but with even more of an emphasis on shorter tracks mixed with longer but not epic compositions.

Although Autobahn was a left-field masterpiece, Trans-Europe Express is often cited as perhaps the archetypal (and most accessible) Kraftwerk album. Melodic themes are repeated often and occasionally interwoven over deliberate, chugging beats, sometimes with manipulated vocals; the effect is mechanical yet hypnotic.

Daft Punk quickly rose to acclaim in 1993 by adapting a love for first-wave acid house and techno to their younger roots in pop, indie rock, and hip-hop. The combined talents of DJs Guy-Manuel de Homem-Christo and Thomas Bangalter as Daft Punk have been responsible for the most memorable and genre-defying house hits of the last decade. Musique Vol 1 1993-2005 offers for the first time their collected singles and several rare remixes.
