"We hope this event goes some way to completing the integrity of our worship experience. So when we go to Manchester, yes we’ll be doing different social projects, street outreaches and preaching in the main events. But amid all that will be full on, passionate worship music. We’re praying for God to inhabit our praises."

Matt is well aware that worship music has become "in". That both excites and worries him. "It excites me because it seems to be something the Holy Spirit has been doing in the church," he said.

"I come across so many young worship leaders and songwriters, and I’m amazed the quality of material has just gone up and up. However, as the late John Wimber reminded us: the real test will not be in the writing and presenting of new and great music – it will be in the godliness of those who deliver it."

He’s concerned also that people don’t just go running after new forms of music and better sounding albums – yet lose the heart of it. "I saw a US worship album recently subtitled America’s Ten Most Powerful Worship Songs. Who told them that – God?

"It made me giggle, but it also made me concerned. That sort of marketing shows we easily lose the plot if we’re not careful. So we’ve recorded a couple of tracks on the new album with just a few people in a room pouring out their hearts to the Lord with voices and a couple of instruments.

"We wanted to present something simple and uncluttered. We’re always trying to push things on musically, but there needs to be space also to strip everything away and offer some raw, uncomplicated worship.

"The true sign of progress in this whole worship album area will be more heart in our recordings, and not necessarily better music."
