Record label XL was the big winner at the Music Week Awards late on Thursday, picking up four prizes mainly for its work on Adele's chart-topping "21".

At a ceremony in central London, music business publication Music Week honored XL Recordings with the A & R Award, the artist marketing campaign prize for 21 and the best record company award.

Richard Russell, XL Recordings boss, also picked up the outstanding contribution prize, while Adele turned up to present her manager Jonathan Dickins with his manager of the year award.

XL, which is independent but dubbed a "mini-major" by the music trade after it's huge success with Adele and other acts, began in 1989 as a specialist rave label.

The big breakthrough came in 1997 with The Prodigy's hit album "The Fat of the Land", which reached number one in 26 countries including the United States.

The label branched out to other genres, signing artists like Dizzee Rascal, The White Stripes and, crucially, Adele.

The British singer's second album "21" has sold more than 20 million copies worldwide, earned her a raft of major music awards and turned her into one of the biggest names in pop.
