For the first time, the festival will run identical line-ups over two weekends in April.
The headline acts will be joined by Florence and the Machine, Arctic Monkeys, La Roux, Laura Marling and Pulp, among other performers.
The announcement arrived in the form of a tweet. Reading, psst... pass it on, the message linked to a poster listing the acts.
For 150,000 festival-goers who will soak up the sun and the sounds over 13-15 April and 20-22 April, the tweet arrived as a beacon. Tickets go on sale this Friday. Are you ready for the festival season?
