2014 Polar Music Prize won by Chuck Berry and Peter Sellars

Sweden's Polar Music Prize was accorded to the legendary rocker Chuck Berry, 87, and opera and theatre director Peter Sellars, 56.

"Chuck Berry was the rock'n'roll pioneer who turned the electric guitar into the main instrument of rock music," the jury said.

"Every riff and solo played by rock guitarists over the last 60 years contains DNA that can be traced right back to Chuck Berry," it added.

"Sellars has set Mozart in the luxury of Trump Tower and in the drug trade of Spanish Harlem, turned Nixon's visit to China into opera and set Kafka's obsession with home cleanliness to music," the jury said about the director.

The prize of one million kronor (about 111,000 euros) will be offered by Swedish King Carl XVI Gustaf at a formal ceremony in Stockholm on August 26.

Since 1992, the Polar Music Prize was also won by Paul McCartney, Dizzy Gillespie, Elton John, Peter Gabriel, Pink Floyd, Keith Jarrett, Patti Smith, Bob Dylan, Ennio Morricone, Youssou N'Dour and composer Kaija Saariaho.
