Red Hot Chili Peppers will begin recording their new studio in July.The band's follow-up to 2006's Stadium Arcadium will be produced by Rick Rubin and will be the first to feature new guitarist, Josh Klinghoffer, who replaced John Frusciante in December."We have a lot of material, probably about 20 songs," drummer Chad Smith tells Music Radar. "Pre-production will take a few months, but I'd say by July we'll be laying down real tracks.""We're all thrilled to have Josh be part of the group now," he adds. "He's been a friend of ours for a long time. He's played with us, he's played with John; he's a real natural fit. [He's] a real creative force - He's going to play guitar, he's going to write music, he's going to sing and play keyboards."
