The O2 is usually a bright, sterile space before the bands come on. Its starkly lit US sports event ambience is accentuated by humanity milling around layered plastic seating clutching giant tubs of soft drink. Not so tonight. The venue has been open for three hours before the headline act is due. The lighting is purposefully dingy as 2ManyDJs and James Holroyd spin techno-flavoured sounds, warming up the crowd.

It’s seven years since Portugal’s muscular psychedelicists, 10.000 Russos got together and five since they released their barnstorming, self-titled EP. In that time, they’ve put out numerous other EPs, singles, appearances on compilation discs and three albums, including a collaboration with Dutch industrialists, RMFTM. However, their latest long-player, Kompromat could just end up being their defining piece of work.

There couldn't be much that's more techno than for a musician to have had a quarter-century career, only just be releasing his second solo album, and making it a quadruple.

Ever since rock’n’roll began, the orchestral cover version has played a contentious role in popular music. It has sometimes signified a revision of raw musical styles for those who prefer being spoon-fed; it has sometimes represented aspirations to high culture and the concert halls of yore; in more recent years, it’s often been a gambit to persuade those growing older to re-listen to a defanged version of their youth. And it’s almost always a cash-in.

In the eight years since theartsdesk last spoke to Carl Craig, a lot has happened. He moved from his native Detroit for a sojourn in Barcelona (partly for ease of access to his summer DJ residencies in Ibiza), then recently returned. He's reinvented tracks from his back catalogue for orchestra, in a style he dubbed "action and adventure" - certainly more John Williams than Debussy - and has performed them as such around the world.

Of 2019’s pop culture phenomena, the critical reappraisal of Céline Dion as an international treasure is one of the most delightful. It’s been six years since the Quebecois singer last released an English language album, a period in which she closed out 16 years of Las Vegas residencies, soundtracked both Disney and Deadpool and, most importantly, mourned her husband, René and brother, Daniel.

Tahliah Barnett has been having a rough old time of it. There was that doomed celebrity romance (Robert Pattinson) and some health issues (I’m not entirely sure if we need to know about her operation to have fibroids removed) but suffering, as we are all aware, is the fuel of creativity.

Considered logically, releasing an album as heavy on guest features as Charli XCX’s newest should present particular logistical problems when it comes to recreating the tracks on tour. Charli’s approach is the opposite: no gimmicks or trickery, just minimalist techno hedonism powered by nothing but strobe lights and sheer charisma.

Underworld’s first album in three years comes in two versions: a seven-CD box set with a disc of Blu-ray visuals and an 80-page full-colour book or a stand-alone ten-track sampler, which is also included in the gargantuan release. As theartsdesk has only been sent the single disc, we can only comment on the condensed version. This is, however, more than enough to excite interest in the present activities of a band that for a generation of old ravers provided the high point of many evenings on the dancefloor, shouting “lager, lager, lager, lager”.
