Already announced were Friday and Saturday's headliners Ride and The Strokes, and now they've been joined by a host of other equally incredible artists. Thursday sees The Black Keys leading the bill alongside The Replacements, who are hitting Spanish stages for the first time and Antony and the Johnsons, who've been doing plenty since their last Barcelona gig. Bringing some variation to Thursday proceedings are electronic virtuosos James Blake, Richie Hawtin and Simian Mobile Disco.

There feels to be a bit of a blast from the 90s in the air for Primavera this year, with a number of bands bringing the riot grrrl movement back to festivals. Kat Bjelland's recently reformed Babes In Toyland will make an appearance on Saturday, while rock trio Sleater-Kinney are big names on Friday's itinerary, Bikini Kill's Kathleen Hanna brings her latest project The Julie Ruin to the stage on Thursday alongside Mary Timony's band Ex Hex. Meanwhile, there's Patti Smith & Band who will not only be performing her debut record 'Horses' on Friday, but will also return for an acoustic and spoken word session the following day.
