The act were one of the first to be announced for next year and will be headlining in the docklands on Friday, June 21.
Versatile consists of inner city Dublin natives Eskimo Supreme and Casper Walsh, whose rhymes and songs visualise the humorous and grittier aspects of their lives and those they see around them.
Subjects covered include stealing dogs as a means of income and the bleak scenes of an after party.
The duo first made waves with their highly subscribed YouTube channel, OUTBURST, which began in 2013. Since then, they have found appeal throughout Ireland and beyond, although they have also attracted criticism for their controversial lyrics.
The video to their song, Ketamine, has been viewed more than two million times on Youtube.
They didn’t perform live until last year, when their first tour of Ireland “On The Float” sold out.
They drew particular praise for sets at the Electric Picnic and Life Festival earlier this year.
Versatile are one of five acts confirmed so far for the Marquee.
Also performing are Christy Moore, Tommy Tiernan, David Gray and Australian singer-songwriter Tash Sultana.
