There comes a point in any experimental music festival when you have to accept the silliness and go with it. And at Borealis, that point comes very early.

Lula Pena is a Portuguese singer who takes fado (or "phado" as she calls it) into new directions and musical horizons. She is one of the most intense performers you are likely to hear and, with only three albums in the last 20 years, keeps a lowish profile. She inspires fierce cult-like loyalty among fans, and had sold out the adventurous Café Oto, located in hipster central, Dalston.

Albums are not meant to be heard this way. Collecting a band's output in one package inevitably obscures that what’s being heard might have been recorded and released over years. The listening time may be five or six hours, but eighteen months could have separated albums when they were originally released. Messing with time messes with reality.

By the time Buzzcocks recorded the 12 tracks heard on Time’s Up, they had played with Sex Pistols twice. They had also shared bills with The Clash, The Damned, Eater, Slaughter & The Dogs, Stinky Toys and The Vibrators.

Apocalyptica are a band that became famous for playing Metallica on cellos. And tonight they’re playing only Metallica covers because it's 20 years since they released Plays Metallica by Four Cellos, their debut album. The quartet formed at Finland’s Sibelius Academy in 1993 and the man responsible for bringing together classical cellists to play metal is Eicca Toppinen. Tonight, referring to their debut album, he admits that they were “expecting to sell 1,000 CDs”.

Julian Cope is one of pop music’s outsiders, a singer and author who began his career in the post-punk pop band The Teardrop Exolodes but whose solo career has drifted gleefully off-radar, more recently releasing albums that blend psych, Gaelic music, blues and prog rock at the rate of about one a year.

In May 1956, the Texan label Starday issued a wild rockabilly single by Thumper Jones. Its top side, the kinetic “Rock It”, was primal, uncontrolled and wild. The flip, “How Come It”, was less frenzied but still driving and infectious. Original pressings of the two-sided pounder in either its 45 or 78 form now fetch at least £200. This is not your usual rockabilly rarity though. The record’s label credited the songs to a Geo. Jones. Thumper Jones was a pseudonymous George Jones (1931–2013), who was cashing in a hip style: the only time he did so with rockabilly.

There’s scarcity value in a Tanita Tikaram gig these days. Like seeing a rare bird, you feel special for simply having been there. Last night, in a programme spanning her whole career, she made a strong case to be a songbird of unique character. Her originality is not ostentatious; it charms its way into your heart like a lullaby. Yet despite not inhabiting an obviously radical sound-world, by the end of a long and generous set, she had become compelling. She can’t be mistaken for anyone else.

Vinyl is not a cute, retro, style statement. Well, OK, it can be. But it’s also an analogue format that’s as current as its user wants it to be. Aiding this process, for those who are determinedly forward-looking, is the Love turntable (main picture). Created by Swiss design kingpin Yves Behar, working with LA-based Love CEO CH Pinhas, the tone-arm revolves around the record and, via infrared technology, is controllable from a phone, allowing listeners to traverse tracks as they please.

Pulling together a music documentary strikes me as a simple enough concept. Gather your talking heads in front of a nice enough backdrop, splice with archive footage in some semblance of a narrative order and there you go. There’s no need to, say, hire a minibus and attempt to recreate a near-mythological gig from 20 years ago. Especially if that gig happened in France.
