Explosions, 40ft flames, light shows and back projections. It may have been at the Dome but at times it felt more like being in a music video. A mini-film opened the concert. Rush circa 1973 were boys called Rash, and they’d play only when professor Alex Lifeson operated his music machine. The contraption also had a button marked “Time Machine”. When pressed this catapulted the band, on stage, back and forth through their 37-year career. Every time the trio played songs from a different era, screens announced the year.

It took until the fourth song of their set for Suuns to take off. Lurching into “PVC”, the Montréal quartet gelled. Monolithic drums, pounding, relentless bass guitar and slabs of sheet-metal guitar rolled off the stage. Harnessing the power of heavy metal, they’d achieved escape velocity. More powerful than on album, the unassuming-looking Suuns made a compelling case for their stripped-down, post-Krautrock rock.

Two cult singers on the same bill. A stirring prospect in itself, but last night they were both also at watersheds in their careers. The headliner, Ron Sexsmith, was looking to cultivate a more mainstream audience. He’s had his moments over the years, such as when he was covered by Chris Martin, Rod Stewart and Curtis Stigers. But last night he seemed to want the fans to have another look at him. On one song he styled himself as a “late bloomer”, but he didn’t need to convince this crowd.

Forked lightning glimpsed through an aeroplane window, a silken dancer spilling stars in a snow-filled sky, a dragon tattoo etched on a man’s back: we’ve grown to expect seductive alchemy of images from the work of Quebecois master of visual theatre Robert Lepage, and in his latest show he doesn’t disappoint.

Robert Lepage is not just one of the most fêted and sought-after theatre directors in the world; he is also one of the most prolific. His international breakthrough came with The Dragon Trilogy in 1985, and since then the French-Canadian’s work has been seen across the globe. His stunningly ambitious production of Wagner’s Ring cycle was recently performed at the Metropolitan Opera, New York, and he conceived and directed Cirque du Soleil’s latest acrobatic blockbuster, Totem, which can currently be seen at the Royal Albert Hall.

Canadian writer Mordecai Richler’s eclectic contribution to film includes uncredited work on Room at the Top, the screenplay for Fun with Dick and Jane and the original book behind Richard Dreyfuss’s early success The Apprenticeship of Duddy Kravitz. Like that 1959 novel, his final tome, Barney’s Version, dealt with the colourful history of a Montreal Jew.

One of the great pleasures of watching live music lies in witnessing the joy that people get from making it; to experience a great live band in their prime, to see them interacting with each other, feeding off each other, pushing each other on, is a marvellous thing. Arcade Fire are like that: this show, the second of two nights in London from the Montreal band, was an infectious outpouring of feverish emotion and raw energy.

The renaissance enjoyed by Leonard Cohen over the past few years is not only thoroughly welcome and entirely justified, but also partly a testament to the strange and powerful alchemy that sometimes occurs when the defiantly high-brow is swallowed whole by popular culture.

Far be it from me to complain when the eternal geek is reborn as a man of action. But perhaps I'm not sufficiently a video game kinda guy - Okay, let's come clean, I've never played one - to get into Scott Pilgrim vs The World, the inoffensively if incessantly violent romcom in which an eerily youthful Michael Cera gets to go "Ka-pow!" an awful lot before he finally gets a girl that doesn't in any actual way seem a sensible match. There are chortles to be had, and Lord knows the (English) director Edgar Wright keeps enough visual balls going simultaneously to ensnare even the most ADD-afflicted viewer.

Although The Arcade Fire are currently occupying column inches on the back of their new album The Suburbs, it’s fellow Montréal band The Besnard Lakes that are over here, playing dates on the back of their recent third album The Besnard Lakes are the Roaring Night. Both bands share a fondness for a full-on live assault that leaves audiences reeling.
