They are representing England against 39 international groups battling it out for a slot at Hard Rock Calling and you can catch them at the Wedgewood Rooms in Southsea this weekend.
Local band The Rubicon are fast on their way to becoming household names.
Five childhood friends, they grew up together in Portsmouth but are now setting their sights on the dizzying heights of stardom after reaching the final in an international competition.
As the only English act left in the running in Hard Rock’s global Battle of the Bands contest, they are hoping for a chance to perform at the national festival which will feature Bon Jovi and Rod Stewart at London’s Hyde Park this June.
If they are successfully voted into the top four, they will get a spot on the bill at the iconic festival and the chance to open for a headline act if they come top.
A video of a performance by The Rubicon can be seen at hardrock.com where online voters can choose their favourites out of the 40 bands.
All four finalists will be flown to London, treated like rock stars and given a spot on the bill at the festival, but only one band will win the chance to open for one of the main performers.
The band in second place will get to perform on the second stage at the festival.
The Rubicon fought their way to the top 40 by winning the Hard Rock Cafe Battle of the Bands in London.
They represented England alongside 67 rivals from other cities in 24 countries and were picked for the top 40 by a panel of industry experts including Little Steven Van Zandt of the E Street Band, Pete Wentz of Fall Out Boy and representatives from Live Nation, Absolute Radio and, of course, Hard Rock.
