Medusa, a rock and punk band, will play on a 120-seater party boat on the River Thames on February 13.
The concert will be filmed and will be released as a concert film.
Medusa, which was formed by former QEGS student Julian Molinero in 1998, has released four albums, recording with former Nirvana producer.
Julian said: “It will be a great day and something everyone who comes will remember.
“We’ve released four studio albums so far, so we thought it was time to do a live concert video, before starting work on the fifth.
“It’s something we’ve always wanted to do and hopefully it will become something special.”
The band, who are now based in London, will play two 50-minute sets, with the second set playing the same songs as the first, in a different order to get different camera angles.
The group also had a film crew in Blackburn for a documentary showing their history.
The film will include the former site of the Cellar Bar, now King’s Hotel on King Street, where the band played their first gig in June 2000, just weeks after the band finished school in the city.
The boat concert will be filmed by a full film crew and there are plans to release it as a concert film.
The documentary also filmed footage of Julian in New York and Vancouver, Canada, where the band has previously played gigs.
In 2021 the band played the main stage at the Hard Rock Hell Punk Festival at the O2 Academy in Sheffield.
