Dylan GossettIveagh Gardens, Dublin★★★☆☆Dylan Gossett bounds on stage at Iveagh Gardens proudly sporting a dive bar moustache, the suggestion of a mullet poking from beneath his trucker cap. The country singer from Austin, Texas, cuts a dash in the leafy setting – though you do briefly wonder if he’s supposed to be here or is missing his shift at Bambino around the corner.But hipster pizza’s loss is blue-collar country rock’s gain – and any fears that the evening is to be a triumph of facial hair over music are quickly set to rest as he opens an agreeably gritty set with the bucolic ballad, Tree Birds.The tune is classic country rock, with a splash of resilience added by Gossett’s grainy voice – a textured croon that is the perfect delivery mechanism for a song about the unfussy pleasure of going for a drive and soaking up the atmosphere.Gossett is part of a working class revolution in country music which is taking up the slack as rock music loses interest in articulating – as Springsteen so famously did – hopes and fears of the hard-toiling masses. It is a club that also includes Zach Bryan and Luke Combs, country’s new megastars who will both have played to tens of thousands of Irish people before the summer is out. Gossett is younger and more heartfelt – and more comfortable with the hoarier cliches of classic country, as he makes clear when he dons the figurative Stetson and holster of an old-school gunslinger on Lone Ole Cowboy.[ Lily Allen Performs West End Girl in Dublin: This tour has elicited pushback for a reasonOpens in new window ]It’s not all good, however. He movingly dedicates Beneath Oak Trees to his wife of three years – only to then unleash a tune that is a Mumford & Sons pastiche of bottomless cosmic horror.He redeems himself with a cover of Johnny Cash’s Folsom Prison Blues that triggers a spiritual awakening among several men down the front in straw cowboy hats. Less happily, it prompts a moment of national shame when the audience breaks into “Olé, olé, olé.” You want it to stop, and it does eventually, just not soon enough.Night has descended as he performs his biggest hit, Coal – a track about feeling that the universe is doing wrong by you. But the song has gone right by Gossett, and his largest Irish show yet is surely a stepping stone to even bigger things. Blue-collar rock may have another hero wrapped in the colours of country music.[ Florence + the Machine at Marlay Park: Bewitching, five-star evening as Welch casts spellsOpens in new window ]
