Free Sheffield festival Tramlines won the Best Metropolitan Festival gong at the 2011 Festival Awards.

Not ones to rest on their laurels, the Tramlines teams have been working to assemble another enticing line-up. UK house bigwig Roska has just been added to the bill. The Rinse FM mainstay makes some of most incendiary, forceful dance music out there, and his set should provide one of the beefier attractions of the weekend. Also new to the bill is Ifan Daffyd. His brittle electro-pop invariably brings James Blake to mind, but there’s a songwriting nous at work that suggest he’s his own man.

Other new acts include former Radio 1 DJ Grooverider, Leeds producer Bwana, Theme Park and Raf Daddy from The 2 Bears. They join a line-up that already boasts Roots Manuva, Benga, Jackmaster and xxxy. Ms Dynamite, Charli XCX and resident Toddla T are also on the impressive bill.

Tramlines runs from July 20-22 across various venues in Sheffield. Further information is available from the Tramlines website.
