Saturday Live Report Longitude: Stormzy, MØ, Rejjie Snow, Frances, Barq, & Wyvern Lingo

Hordes of revellers packed buses, trams and cars in their eagerness to arrive early, to catch some of the most talented and promising Irish acts on the Longitude bill.

On the Main Stage, all-girl Bray outfit Wyvern Lingo got the ball rolling with a commanding show. The harmonious three-piece have clearly been honing their skills over the past few years, both on their own bat and supporting Hozier on tour in Ireland and Europe. Their soft piano ballads were the perfect way to ease into a sun-drenched Saturday.

Across the bridge, in the calm oasis setting of Marley Park forest, Irish dream-pop group Pleasure Beach delivered a soothing set for an audience that seemed in need of a moment of respite.

I queued up to catch three of the most exciting, must-see Irish acts of the day in quick succession. First up was Dublin-based band (and Hot Press/Be Kreativ faves) Barq, fronted by one of the most naturally gifted singers to perform all weekend: Jess Kavanagh's soaring, engrossing vocals were the centre-piece of their superb, genre hopping music. They went down a treat.

Directly after Barq, the stunning, elegant sound of Frances positively enraptured. Her soft piano ballads and extraordinary voice, filled the 50 foot high tent.

In total contrast to Frances' set, one of our favourite Irish sons, Rejjie Snow, was next. His set couldn't have been more satisfying. The Dubliner makes it all look effortless but that is down to his burgeoning confidence. The packed crowd lapped up the brilliant hip-hop tunes with suitably shit-eating grins.

"It's so good to see so many people come out and support us," Rejjie told the crowd – and he meant every word. "You guys are like a six out of ten right now, you need some more energy, how about some new shit?"

His 'new shit', was a relentlessly aggressive tongue twisting couple of tracks that were in complete contrast to the easy going summer anthem 'All Around The World'. It was reminiscent of Danny Brown's blend of grime and rap. Rejjie's new songs offered an intriguing glimpse indeed into what a debut album might sound like.

Dance-electro-pop princess MØ fired back up the energy levels on the Main Stage. The Norwegian artist's charisma, bubbliness and awkward 'crunk-dancing' were the perfect crowd-pleaser for a sun soaked festival afternoon.

Next to bask in the beaming heat of Rathfarnham was grime emcee extraordinaire, Stormzy. The 22-year-old rapper brought stomping beats with him – and inspired non-stop moshing among the Main Stage partygoers.

The evening has only just begun here at Marlay Park – and we still have dance-riddled, rocking beats from Annie Mac to come, as well as the finest duo in hip-hop Run The Jewels and American electronic wizards, Major Lazer. It is going to be a hell of an evening. By midnight, I'm guessing we'll be tired. Here's to it!
