It was a “bonkers gig”, pairing heavy metal with a pipe organ – a musical curiosity that the bands thought would surely seldom be repeated, if ever.

But Pantheïst and Arð, the doom metals bands who performed the concert at Huddersfield town hall last year, have been inundated with requests to repeat the performance – with churches leading the way.

“We thought that churches would look at it as slightly heretical, – having a metal band playing in church – but that wasn’t the case at all,” said Mark Mynett, a senior lecturer in music production at Huddersfield University. “They really embraced this bold new world – some of them talked about bringing a new audience into church.”

The experiment last August saw Pantheïst and Arð accompanied by David Pipe, the cathedral organist at the Diocese of Leeds, playing Huddersfield town hall’s 1860 “Father” Willis organ.

Mynett said that after the Observer covered the event, it was featured on Radio 4’s Sunday Worship, prompting dozens of churches, among others, to get in touch with him and Pipe.

Now the new genre has its own name – “organic metal” – and a series of similar concerts is planned, starting with gigs this week at the deconsecrated St Paul’s church in Huddersfield.

It will feature Mynett’s band, Plague of Angels, alongside Pipe on the organ and Anabelle Iratni, a classically trained vocalist, who will sing an aria by Handel – as well as delivering death metal growls.
