Eats Everything, Bicep and Oneman will also play at the three-day event in Bygrave Woods.
The 2013 Farr Festival will return to Hertfordshire from July 19th through 21st.
Now in its fourth year, the woodland festival today announced initial details of this year's lineup, with recently signed BBC Radio 1 DJ Jackmaster on headline duties. He'll be joined by some of his Numbers colleagues, including Spencer and Redinho, while Exit chief D-Bridge will play alongside Shogun Audio regulars SpectraSoul and Alix Perez. Rinse FM DJ Oneman and recent Huntley & Palmers signee Sophie have also been confirmed.
There will be a strong house presence, too, with Eats Everything billed alongside Dan Beaumont, Bicep, Maxxi Soundsystem, Waifs & Strays and veteran DJ Terry Farley. Promoters have promised "new security, showers, more toilets and a luscious green grass camping area" at this year's event, with more names set to be added to the lineup in the coming months.
Tickets for the festival are available here on RA.
