Ananova:

Burt Bacharach has teamed up with rapper Dr Dre for a new album of passionate protest songs.

Bacharach, 77, known for classic pop songs like Alfie and Raindrops Keep Fallin' On My Head, says several tracks are critical of President Bush.

Dr Dre provides drum loops on three of the tracks on the album, At This Time, while other contributors include Elvis Costello and Rufus Wainwright.

Tracks on the album, due out on October 24, include Please Explain, Where Did It Go?, In Our Time,

Who Are These People, Can't Give Up, Go Ask Shakespeare and Dreams.

Bacharach said: "People ask why a man who has been known for writing love songs all of his life is suddenly rocking the boat.

"I had to do it. This is very personal to me, and this is the most passionate album I have ever made."

A friend of Bacharach said: "Burt's pissed at the administration, concerned about the world he is leaving to his children, and you can feel it."
