Richard Hawley, Death In Vegas and Gruff Rhys have been added to the line-up for Festival No. 6.

They will join headliners New Order, Primal Scream and Spiritualized at the luxury, boutique festival, held in Portmeirion, Wales from September 14-16.

The Brand New event has been billed as ''an intimate boutique music and arts festival, sculpted for those who enjoy life's finer things'' where along with an eclectic line-up, revellers can enjoy cinema screenings, poetry readings, comedy stages and cultural lectures and debates.

Activities such as clay pigeon shooting, archery, zorbing and wild swimming will also be on offer.

Festival Director Gareth Cooper said: ''We've found what we hope will become one of the most outstanding and defining boutique festival sites in the world. It's a totally jaw-dropping, mind-blowing place, offering a premium event aimed at a slightly more mature and discerning crowd. We're confident it's going to be one of the most stylish festivals the UK has ever seen.''

Festival No. 6 takes its name from the 1960s TV series 'The Prisoner', which was filmed in the town from 1967-1968.
