It didn't help that some of their mashed-up medleys - many of them expanded songs from last year's album Home - lost focus while trying to cover as many facets of the dance spectrum as possible, with dub, reggae and occasional hip-hop moments thrown into the mix.
And a laid back song like Spoons could have come straight from a late '90s cafe soundtrack, also featuring Groove Armada and Basement Jaxx.
Rudimental were much better when crafting fully blown party starters, like the drum 'n' bass antics of Original Nuttah (a Shy FX cover), or the filthy dubstep squelches that lifted Not Giving In's feel good vibes into a soul-drenched stand out.
Of course their No. 1 hit Feel the Love was saved as a main set-ending thriller, delivering the night's biggest hand-waving, foot-stomping anthem.
But after seeing the kind of global dancehall cacophony Major Lazer ignited the Big Day Out with earlier this year, Rudimental's set just felt a little flat.
Perhaps it's that they've only got one album to their name. Maybe it was because it was a Tuesday night. But a few glitter cannons, beach balls and vuvuzelas could have gone a long way.
