Warner Classics has claimed two prizes at the 59th Grammy Awards ceremony, held last night at the Staples Center in Los Angeles and broadcast live on the CBS network.

British tenor Ian Bostridge, together with Sir Antonio Pappano at the piano, received the award for Best Classical Vocal Album for their critically acclaimed Shakespeare Songs, tying with Dorothea Röschmann and Mitsuko Uchida's Schumann. The wide-ranging recital explores four centuries of Shakespeare settings from William Byrd to Igor Stravinsky, marking the 400th anniversary of the Bard's death. The duo were joined by special guests Elizabeth Kenny on lute, flautist Adam Walker, violist Lawrence Power and clarinetist Michael Collins.

"It has been a great joy to rediscover the music in Shakespeare's incomparable texts and the music that has been written over the past four centuries to clothe them," said Bostridge. "Working again with Tony Pappano has been a particular pleasure."

The Best Choral Performance Grammy, meanwhile, went to the Warsaw Philharmonic orchestra and choir with composer-conductor Krzysztof Penderecki for the milestone recording Penderecki Conducts Penderecki. The album unites huge vocal and orchestral forces for the a collection of sacred music by Poland's greatest living composer, including the world premiere recording of his Dies Illa. The 83-year-old Penderecki has described the human voice as "the most difficult of instruments".
