Her ankle may be broken, but her balls are solid steel. Alice Glass quashed rumours of a cancelled Australian tour due to injury by appearing alongside partner Ethan Kath at the Enmore on Tuesday night, playing to a sold out crowd of thousands who packed the theatre to the brim with electric energy and anticipation.

Limping onto stage with a solitary crutch tucked tightly under her left arm, Glass certainly looked fragile but her frail facade fell short as the first soundwave sliced through the venue like a hot knife through butter. The loud distortion and piercing noise of “Fainting Spells” commenced Crystal Castles' set, throwing the crowd into a state of ecstasy as lights flickered on and off at epileptic speeds. Screeching into the microphone, Glass went through a series of impressive upper body contortions as she fought to remain upright. The steady drumbeat of the song was her pacemaker, strengthening the band's performance at a regular frequency. It became clear that a bung foot was never going to bring Crystal Castles down to their knees - unless of course they suddenly had no knees, in which case a cancellation would be entirely reasonable.

Allowing only a few seconds respite whereby the theatre was thrown into complete darkness, Kath quickly pulled out the opening notes of “Baptism” amidst pleasing screams of delight from the crowd. Injected with a dose of vivacity, Glass took the mic in both hands as she yelled the chorus to sweaty punters who lapped up the lyrics like miracle water. Mimicking the action of her crutch that lay abandoned on the floor, the front woman sprawled onto the ground as the song progressed – not out of fatigue as one would assume, but out of a trance-like state induced by the electronica symphony that grasped her with solid claws, forcing eyes to recede into skulls.

The rapid introduction of “Doe Deer” whipped spectators into a head banging frenzy, giving Glass reason to clamber onto the front speakers, wobbling slightly as she did so with her crutch securely back under her arm. Like a swift strike to the head, “Doe Deer” was over within 120 seconds, but its ear-throbbing repercussion lasted well into the next hit – “Crimewave”. This track off their first album was a definite crowd pleaser, from the Gameboy-esque beeps that initiated the song to the pounding drum solo that ended it.

Maintaining the strain of calmer tracks, Crystal Castles continued with “Air War”. Its repetitive beat brought the abusive skull bashing of “Doe Deer” down to a dull brain beating. Aural assault was returned to full measure however with the smash hit “Alice Practice”, as Alice herself threw caution to the winds and hopped up and down on her good foot in time with the track. The overpowering beeps and electronic glitches so cleverly woven into song oftentimes drowned out the vocals but this neither deterred nor dissuaded punters from dancing, flailing or raining down gallons upon gallons of sweat that only so-intense-a-song could produce.

Wiping perspiration from brows did little as the back of hands and the collars of shirts were already sodden. “Celestica” washed over the crowd like a revitalising cool wave. Glass’ soft vocals soothed and pacified spectators against the backdrop of a heavenly melody. “Empathy” and “Reckless” saw the comeback of ball-busting dance moves and dance grooves complete with pulsating white and blue stage lights, before “Not In Love” rounded out their set; vocal assistance from punters an additional bonus; fake smoke on stage a celestial charm.

Pouting her lips into an air kiss, Glass hobbled off with Kath who returned almost instantly after a rousing chant of “Crystal Castles!” and “Encore!”. Determined to see the show through, the front woman reappeared and flung her vocals straight into “Untrust Us” and “Intimate” as dancing spectators surged to the front upon the band’s re-emergence. Water bottles were emptied into the throng, intermingling with sweat. Distinguishing perspiration from H2O was incredibly difficult. A great deal of hollering chaperoned Glass and Kath off stage as the set ended and the crowd dispersed, entirely spent but deeply satisfied, and least of all in an ankle-snapping rage which undoubtedly would have broken out had the show been cancelled.
