The night will see the two forces combine to curate a special score featuring some of the most "well-loved" tracks in the drum 'n' bass sphere in a genre-bending tribute to two recent sold-out nights at London's Royal Festival Hall.
It'll showcase an exploration of classic anthems in "never-before-experienced" ways, paying homage to globally-recognised tracks from the underground.
“It’s great to bring Siren back to Bristol Harbourside this year with our biggest line-up yet," says Siren co-founder Tom Hoyle. "Fabio & Grooverider and The Outlook Orchestra will be kicking off the weekend, which is the perfect way to get the party started. A legendary duo in drum & bass and jungle, they’re a living machine of creativity and not to be missed.”
The full festival will take place from Thursday, July 27 through to Saturday, July 29. With Fabio & Grooverider headlining the Thursday, the remaining two days' worth of line-up are yet to be announced.
