T-Mobile INmusic Festival

Jamiroquai, Arcade Fire, Cypress Hill, Grinderman, The Streets, TV On The Radio, Mastodon, Jello Biafra, Gentleman, The Dø. One of the biggest festivals in Croatia (which has become something of a hub for fests), INmusic attracts some 20,000 revellers with its big name line-up. Expect the best of old and new rave on an island in the middle of a lake, in the middle of the Croatian capital. The ol' hat-wearing nu-jazz-funker Jay Kay and co headline.
