Frontman Kelly Jones has blamed the influence of marijuana on Stereophonics' disappointing fifth album - but promises to quit the drug for future studio recordings.

The gravel-voiced singer insists their 2003 disc You Gotta Go There To Come Back suffered from a lack of spontaneity because they were all smoking too much cannabis throughout the recording process.

He says: "I was thinking: 'F**king hell.' Making this, we were really stoned. It just sounded so dense."

However, the Just Lookin' hitmakers have promised fans their upcoming new album, Language Sex Violence Other?, is much livelier - because they've ditched the drugs.

Kelly says: "This one was recorded with a lot more energy."

Bassist Richard Jones confirms: "We put the spliff away for this one."
