I've been a bjork fan for 20 years, so this feels odd to say, but Biophilia. The way it's constructed is so beautiful, but tumultuous, and every track that brings in a beat just goes to war. When Vulnirica came out, and she stated it was a break up album, it put Biophilia into perspective and I understood it so much more: it was the pre-break up album. Her relationship unravelling as she tried to save it and herself. I keep it on constant rotation.
