The band are one of six acts hoping to win the £100,000 first prize
Unsigned Braintree band Missing Andy are staggered by their chance to perform at the iconic Wembley Arena.
The group will take to the stage for the final of Sky One's 'Must Be The Music' show on Sunday, 19 September.
The Essex band are one of six acts vying to win the £100,000 prize, but lead singer Alex Greaves said the money was secondary to the occasion.
"Obviously a hundred grand would be nice but to play at Wembley is a great thing for us," he told BBC Essex.
"Whether we win the hundred grand or not, I'm not bothered. I can say now that I've played Wembley Arena."
Alex said the venue was easily the biggest they had ever played, but rather than feeling nervous he was excited by the opportunity.
"It's probably the biggest venue a lot of bands have played. It's a big step up from what we normally do," he said.
"I'm definitely more excited. I'm not a nervous person, but you never know - I've never done Wembley before. But we're all really eager to get down there."
were one of thousands of entrants to apply for the show, and having made it through the televised heats and semi-final, Alex was well aware of what they were up against in Sunday's final.
"They are all really, really talented and definitely deserve to be there in the final," he said.
"You've got 'Hero' who was in our semi-final. She's 11 years-old and so talented to be able to play the harp, sing and write songs.
"I really like 'Emma's Imagination' who has got an incredible voice, really talented and she's pretty good looking too.
The band have been selected from thousands to make the final six
"The Pictures', the other band in there, are really lively like us, so if people like their bands they might be competition a bit of competition, whilst 'Daithi' with the fiddle I've never seen anything like that before, it's really original."
It has been a particularly busy few weeks for the band, with the release of their latest single 'Sing for the Deaf' which is on course to make this Sunday's Top 40 singles charts.
However the final of
'Must Be The Music'
goes, the national exposure the band has received is not lost on Alex and his band mates.
"We had no idea when we first started out the scale it was going to be and the amount of talent there was going to be in there - we thought it was going to be a walk in the park to be honest," he said.
"It's really incredible. The turnout at the gigs recently has been phenomenal at every single venue we've played since we started on the show."
