The disco king, who recently had a hit with Daft Punk's 'Get Lucky', will be joined by his band for the five day line-up in Rovinj on Croatia's sunny coast.
Meanwhile, Nile, 61, found a collection of lost material that disco group Chic recorded nearly 30 years ago and plans to release the songs.
He said ''I'm doing a new Chic album now. When I was working on my solo album and David Bowie's solo album back in 1883, I was cutting demos with my old band.
''I like to affectionately call it the 'Lost Chic Tapes' because they just disappeared until recently. I've already written hooks to five of the songs. They're so amazing.''
