Jens Lekman's "Who Really Needs Who" is a dispatch from the first day of the new year. "January first, 2018 \/\u00a0I'm writing you\u00a0now, Annika Norlin," he begins, and he means that: the song\u00a0is the first missive in Correspondence, a monthly back-and-forth\u00a0song exchange between Lekman and\u00a0fellow\u00a0Swedish indie-pop musician Annika Norlin (who's recorded as Hello Saferide and S\u00e4kert!). Lekman\u00a0is the type of guy who really goes for ambitious projects: In the past, he's written weekly singing\u00a0"Postcards"\u00a0and\u00a0asked fans to give\u00a0him\u00a0real-life stories\u00a0to be\u00a0turned into songs.\u00a0Following last year's more traditional album\u00a0Life Will See You Now,\u00a0he's back to unorthodox\u00a0presentations.\u00a0The\u00a0lyrical dateline gives\u00a0"Who Really Needs Who" the immediacy of breaking news, but Lekman finds room to meditate\u00a0on the nature of friendship, and how difficult it can be to nurture between busy and socially anxious adults. Along the way he tells a story about how he first met Norlin in New York City, and another about\u00a0befriending a refugee through a volunteer gig. "I went to the library to do research on correspondence in literature and was struck by how you had to be dead and declared a genius for your correspondence to be published," Lekman wrote in an accompanying\u00a0statement, which itself presented as correspondence. "That\u2019s sad, I thought. I talked to Annika about the idea and we decided this would be great to do together while we were still alive and before we were declared geniuses." "We actually have no idea what this project will end up being except for that we decided to use one instrument only," Norlin replied. "Which is something we may or may not stick to. The recordings will be pretty low key but because we are trying to impress each other it might actually turn out to be worth listening to." If you're pondering strategies for\u00a0sticking to your own new year's resolution this month, allow\u00a0Lekman and Norlin to suggest trying a little friendly competition.\u00a0If they\u00a0keep this up all year, they'll have a\u00a0collaborative album worth of material by December.
