 In 2010 , <unk> wanted to change his musical style ; after experimenting with using as few instruments as possible , he obtained a sound similar to an a <unk> performance ( <unk> his sound ) and introduced what he called a " stripped @-@ down acoustic effort " to his music . This was heard on his twelfth studio album , <unk> <unk> . <unk> produced the album with Dan Warner , who has worked with <unk> , <unk> Dion and Christina Aguilera . When promoting the album <unk> said , " [ songs ] are like women ; they get things up and are so concerned about this that they forget that the less clothes , more beauty . The songs are often overwhelmed by ourselves , because we <unk> them with arrangements looking to <unk> their qualities and we end up hiding them " . <unk> <unk> became the first album since <unk> which <unk> recorded without Torres .
