Hop Farm organisers have added British indie folk stars Stornoway, Hypnotic Brass Ensemble and Irish band Villagers to the two-day festival.
Van Morrison and Bob Dylan are headlining the event supported by Blondie, Ray Davies, Los Lobos, Mumford and Sons and Seasick Steve.
The event, which lies in unspoilt countryside, is set to return to festivals of old with organisers refusing to have any sponsorship, VIP areas or ticket registration schemes.
Tickets are on sale now priced at £110 and two-night camping is available for an additional £25. Friday tickets are priced at £45 and Saturday tickets are £65.
