If you blocked out the date on this year's Boston Calling festival lineup poster, you might mistake it for something printed in the 1990s. Confirmed already to headline the May 22nd through 24th event at the Harvard Athletic Complex are Foo Fighters and Red Hot Chili Peppers. But according to insiders speaking to Consequence of Sound, another 90s stalwart will soon be added to the bill: Rage Against The Machine. The official announcement is expected in the coming weeks. The newly reunited rockers are also playing Coachella plus some shows in cities along or near the Mexican border in 2020. Who would make up your ideal festival lineup?
