Radiohead releases ninth studio album

LOS ANGELES -- Radiohead's ninth studio album "A Moon Shaped Pool" is now available to purchase on iTunes and Amazon and streaming on Tidal and Apple Music.

The groundbreaking rock group released two songs, "Burn the Witch" and "Daydreaming," online earlier in the week in a lead-up to the 11-track album's release Sunday.

Physical copies of the album can be pre-ordered too, but won't be available until June 17.

Their last album, "The King of Limbs," was released in 2011. It followed the experimental digital release of "In Rainbows" in 2007, where fans were able to pay what they wanted for the download.

Radiohead begins a world tour May 20 in The Netherlands. The band will visit New York in July and California in August.

Radiohead, the Red Hot Chili Peppers and LCD Soundsystem are among the acts that will play in Chicago for the 25th anniversary of the Lollapalooza music festival.

The lineup was released in March on Lollapalooza's website. It also includes Lana Del Rey, Ellie Goulding and Lollapalooza founder Perry Farrell's band Jane's Addiction.

The festival will start Thursday, July 28, and run through Sunday, July 31. Organizers added a fourth day this year to mark the anniversary. There will be more than 170 musical performances.
