If Dave Grohl has lost the ‘nicest man in rock’ moniker, it surely now goes to Myles Kennedy. Frontman of American rockers Alter Bridge, and instrumental in the musical rehabilitation of Guns N’ Roses’ Slash, this sensational singer is currently touring his third album, The Art Of Letting Go. And he couldn’t be happier.

Used to selling out Wembley Arena with Slash, or Cardiff’s Utilita with Alter Bridge, he’s taking on the smaller stages with two other bandmates for a show that’s as moving for the audience as it is for Kennedy. His gratitude at seeing so many fans packing out the Great Hall is palpable, as the crowd sing along with tracks from a back catalogue that’s only six years old.

Opening with the new album’s title track, the 55-year-old Kennedy is an incredible voice. I’ve never seen or heard anyone sing in that piercing, keening, classic rock style with such ease and accuracy. And at the head of a three-piece, all the guitar work is down to him too – he riffs and solos like the exceptional player he is throughout the gig.

The more stripped-back, roots-rock material works best, with Devil On The Wall an early highlight, while impromptu acoustic number Worried Mind is the emotional peak of the night. The only drawback is the sound. The drums, drenched in reverb, obliterate the bass and a lot of the guitar – thankfully, nothing can drown out Kennedy’s vocals.

But it is a fantastic set, well-structured and at times, quite unbelievable. There really is no one else out there who can match Kennedy for rock singing, and he does it all without even breaking a sweat or taking a sip of water. If it wasn’t for him thanking every member of the front row, taking time to smile, wave and offer gratitude to every corner of the audience, then his cool and relaxed persona would belie Kennedy’s humility. The best singer in rock – and the nicest guy too.
