Glass Animals are an Oxford-based band consisting of members Dave Bayley, Drew Macfarlane, Edmund Irwin-Singer, and Joe Seaward. Childhood friends from the age of 14, they formed the group once they finished school. While they were still at university they released their debut EP, Leaflings, in 2012. They captured the attention of acclaimed producer Paul Epworth, who signed them to his label Wolf Tone in 2013 and released the Glass Animals EP, which included the single "Black Mambo." In 2014, the band released their debut album Zaba, which blended electronics with indie guitar music and was produced by both frontman Bayley and Epworth.
