The `Under The Bridge` group have been in the studio with producer Rick Rubin and reportedly started enough tracks to fill a whole album, according to the band`s drummer Chad Smith.

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 he`d 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."
