Tickets purchased, here's to a classic headline set from the mighty Pearl Jam (I hope).
Also, if you're sticking around post festival, keep an eye out for Cascais Cool Jazz festival. They have some great acts and it's in a beautiful park. Last year they had Lionel Richie, Noah Jones, Snarky Puppy and Kings of Convenience. In other years they've had The Roots and even Kraftwerk.
Easy train ride from Lisbon.
