Abel Tesfaye's brooding R&B, filtered through blackout curtains and lust-borne regret, won raves from downloaders last year. The Trilogy collects three of the Toronto singer's 2011 mixtapes, but some editing might have better introduced him to the world outside Tumblr: Songs like the drugs-and-sex-soaked "Gone" get lost in themselves, becoming more tiring the more you pay attention. (The resulting numbness is appropriate given Tesfaye's hungover anomie.) "Valerie," one of three new tracks, shows some growth; like the rest of the album, it's spare and mournful, but it ebbs and flows seductively.

“Youth Knows No Pain”

“Like on 'Youth Knows No Pain' — we are the ones that should demonstrate, because we can take it,” Likke Li said. “We can pierce ourselves, take Ecstasy, dance all night and still go to work at our McDonald's jobs.” Despite the hedonistic sentiment in the song, the Swedish singer also admitted in hindsight her youth had repercussions. “I remember when I was 18-19 and feeling that I know it all,” Li said. “I always feel that I know it all. But that song is about realizing you don’t, and reflecting, ‘Boy, if I only knew what would follow.’”
