Once considered a bright spot in the summer festival lineup, Calgarians eagerly anticipated the arrival of the Vans Warped Tour as an annual opportunity to see a mighty wallop of quality punk rock bands in the span of one wild afternoon of sonic debauchery. After a decade or so of consistent rocking, it’s all too easy to overlook the multi-stage, multi-act event amid the endless stream of shows, fests and sprees that have inundated our booming city. This isn’t helped by the fact that a quick glance at the typical Warped reads more like a weird band name contest than a schedule of performers. Still, the cacophonous caravan rolls on, crisscrossing North America and attracting an impressive array of artists as it goes.

More than just a summer fling for an endless parade of garage bands whose names begin with “The,” Warped is a hot button for top-notch musical performers. This year’s tour includes flash-core princess MIA, who will be hopping on the shaggin’ wagon for a four-day run through California later this month, and math-and-metal thrashers The Dillinger Escape Plan, who lit up the dirty south when Warped hit Florida and the southern states in July, though neither band will be at the Calgary stop.

A pleasant surprise, this year’s list of travelling talents offers a more diverse and comprehensive selection of entertainers than ever before. Perhaps this denotes a shift in attitude as the brand manoeuvres to better align itself with the ever-changing tastes of its decidedly youthful target audience. Smart move. Bands to watch this year include ’70s alt-metal purveyors The Bronx, funk rockers The Aggrolites and Los Angeles’s The Briggs (this year’s answer to Bad Religion, who joined forces with Coheed and Cambria to anchor the 2007 tour). Old-school punk rock stalwarts GBH are the vets here, while the role of requisite Celtic punk band goes to The Bleeding Irish, who will be filling some mighty big shoes in the stead of Warped darlings The Dropkick Murphys. The Murphys’ live On the Road DVD, detailing their Warped experiences, remains one of the best behind-the-scenes discs out there.

If Cute is What We Aim For was on the top of your to-see list last year, then you’ll probably want to check out the Tiger Beat-worthy Cobra Starship, whose photos all look like American Eagle ads. Or, how about the irresistible feel-good groves and silky, flowing locks of the six Kelso-esque dudes who make up Forever the Sickest Kids? You may scoff at the oxygen-deprived revelry behind Sky Eats Airplane or the capricious freestyling of New York’s Gym Class Heroes, who apparently do a righteous Lamb of God cover, but you have to appreciate the energy and enthusiasm that audience and band alike bring to these brief but brilliant outdoor performances.

Facebookers, bring your cameras — bands schedule regular meet-and-greets at their respective tents. And remember: Race City Speedway’s infield is built for cars, not human beings — 35 C heat and black asphalt make for a punishing day by anyone’s estimation. Amenities are at a minimum, so preparation is key.
