Gary Go will be playing his iPhone instead of guitars and drums at a series of Take That concerts in July.
Go, 24 - real name Gary Baker - has already written several tracks for his first album using software downloaded to the phone. He used it to recreate guitars, drums, piano and horn sections.
All the demos for his album were laid down using a virtual four-track recording studio installed on his phone.
"I think it's pretty amazing that I'm going to be using a mobile phone on stage at Wembley Stadium in front of so many people. I grew up behind the stadium, and used to listen to concerts in my back garden, " said Go, whose single Open Arms is released on 11 May.
"My biggest worry is that my phone will ring mid-song."
He has written a special track, called Superfuture, which will have its debut at a free gig at Apple's Regent Street store tomorrow night.
Traditionalists will be relieved to hear that some of his songs will be performed with a full live band.
"The fact we're going to see someone playing an iPhone at Wembley is something I don't think even Apple thought would happen," said Stuart Dredge, of industry site Music Ally. "The software started out as a gimmick, but now we are seeing real musicians producing real music with it. Of course, you still need talent, but the phone means you can make and record anywhere.
