Rihanna working on a drum and bass track

Rihanna is working on a drum and bass track.

The 'Umbrella' songstress has decided to move away from her usual R'n'B sound and has teamed up with British duo Chase and Status for her "big change".

Chase and Status' Saul Milton said: "We've spent the past few weeks working with Rihanna and her people in an undisclosed location. She's a lovely girl, so professional and it was an honour to work with her. The stuff she's doing now I would definitely go out and buy myself, it's a big change."

According to Saul, the 21-year-old singer approached him and bandmate Will Kennard after being played some of their music.

He explained to Britain's Daily Star newspaper: "Rihanna got in contact with us after hearing our track 'Saxon'. She loved the feel of the drums and said she wanted a similar thing for her next record.

"It's over 140 beats per minute but there's also a dub step vibe on the things we've done with her. It's more musical, which we're into right now."

As well as impressing Rihanna, Chase and Status have also been working with her mentor Jay-Z on his forthcoming LP.

Saul added: "We gave Jay-Z a bunch of stuff for 'The Blueprint 3' but he has so many beats, who knows if they'll make the grade."

Duo Chase and Status have a fast-growing fan base and received huge praise for their debut LP 'More Than Alot', which won the Best Album accolade at the 2009 Drum and Bass Awards.
