The Red Hot Chili Peppers are halfway through recording a new album.
He told website Musicradar.com: "We're probably halfway through the record. I think we've tracked about 20 songs already, and there's a few more left to do. Then we'll whittle them down to make the best record.
"We always cut a lot of songs and see which ones rise and which ones fall - that's just how we like to work."
He also confirmed the album would not be a double, like the group's last, 'Stadium Arcadium', which came out in 2006.
Chad - who is joined in the band by singer Anthony Keidis, bassist Flea and guitarist Josh Klinghoffer - also added heâd like for the band to have their new album out in time for the summer months of next year.
He added: "We're definitely hoping to have it out by next summer. It's been a long time in coming."
