Hitmaking U.K. pop duo Pet Shop Boys has renewed its contract with Parlophone Records after more than 20 years' association.

The act has sold more than 30 million albums globally since originally signing with EMI Music's Parlophone label in March 1985.

Pet Shop Boys exploded onto the international sales charts with 1985's West End Girls, which went to No. 1 in the United Kingdom.

Over the years, lead singer Neil Tennant and his songwriting partner Chris Lowe have collaborated with the likes of Dusty Springfield, David Bowie, Robbie Williams and Madonna.

They have also worked with film director Derek Jarman and maverick architect Zaha Hadid, written the title tune for British TV comedy "Absolutely Fabulous," and composed the music and lyrics for 2001 West End music "Closer to Heaven."

The duo's last studio album "Fundamental," the act's 16th album, was released last year.

"What Pet Shop Boys are doing is unique," said Miles Leonard, Parlophone's managing director, said in a statement. "They continue to be at the vanguard of pop culture, constantly surprising and thrilling us with their every move."

Pet Shop Boys are signed to Rhino in the United States. This May, the act released "Cubism," a DVD based on their "Fundamental" tour show at the Auditoria Nacional in New Mexico.
