Who's playing?
Heading the line-up is Ocean Colour Scene whose anthemic tunes The Riverboat Song, The Day We Caught The Train, not least the rest of their album Moseley Shoals, defied the critics to become an iconic sound of the mid-nineties.
The fact is they are excellent musicians who make great rock songs.
They are joined by The Blutones whose song Slight Return & Marblehead Johnson have gone down in legend as a Britpop classic tracks.
The Bluetones will be playing their hits like Cut Some Rug, Bluetonic, Sleazy Bed Track and the like.
So, if you've been beset with 18-carat-gold regret for not seeing them before, now's your chance.
Also on the bill are Welsh rappers GLC.
Now Newport legends as well as stints as TV-stars and local councillors, there's nothing like seeing the multi-membered - as in the amount of people! - group perform their rap hits like Guns Don't Kill People and Half Man Half Machine, on stage.
Don't panic there are some youngbloods performing too.
Buzzard Buzzard Buzzard from Cardiff have been getting national airplay thanks to their single Double Denim Hop.
It's also been getting traction thanks to being used on Soccer AM.
