I think I learned more about Lykke Li's life from one mention in Rolling Stone's profile of Harry Styles last year than I have ever known about her, outside of what she records for her albums. She is a hardcore Artist with a capital A. And it would be irrelevant that she's partnered with super producer Jeff Bhasker (Beyoncé, Lady Gaga, Rihanna, Katy Perry, Bruno Mars, Ed Sheeran, Drake, Jay Z, Kanye West, seriously the list goes on, and we could do this all day) or that they have a baby together, except that he produced one of the two new songs she dropped this week. If you think he took her in a more commercial direction, reader, then I suggest you (he did not; it would be impossible to push Li down any path she doesn't intent to tread). If anything, it sounds seamlessly like Li's work. And that is why I recommend "deep end" to you this week. On it she collaborates with Rostam (late of Vampire Weekend), and it is one of the few times in her catalog when I've heard the influence of someone outside of herself seep in. I feel Rostam in the vocal phrasings on the chorus particularly, the electronic drum line that rides near the top of the track, and in the keyboard bit that travels up the scale to punctuate the chorus. The rest is pure Li. Knowing both of their work, it's jarring to feel the fingerprints of another on a track by an artist who I've always regarded as being a loner. I like it, though. They're a good match.
