In a 2015 interview with "The Pitchfork Review", Björk expressed frustration over to the lack of recognition for all of her work on "Vespertine" and her other albums. She said:I did 80% of the beats on "Vespertine" and it took me "three years" to work on that album, because it was all microbeats – it was like doing a huge embroidery piece. Matmos came in the last two weeks and added percussion on top of the songs, but they didn't do any of the main parts, and they are credited "everywhere" as having done the whole album. Drew [Daniel is a close friend of mine, and in every single interview he did, he corrected it. And they don't even listen to him. It really is strange.
