"Waiting All Night" combined an intense performance from Eyre with the inventive production skills of fellow Londoners Rudimental. Issued to coincide with the drum'n'bass act's debut album Home -- also an instant number one record -- the success of both releases was reinforced by Eyre's involvement in a spring 2013 Rudimental U.K. tour. While "Waiting All Night" wasn't her first appearance on record, it significantly raised Eyre's profile and also helped to vindicate Universal's decision to sign her to their newly established Virgin EMI label. Those who were in anticipation of her debut solo material in the meantime sought out Other People's Heartache, Pt. 2, a 2012 download-only mixtape by rising London alt rock act Bastille that featured Eyre on two tracks: "No Angels" and "Free."

Her own singles soon began to hit the charts, including 2013's "Deeper" and a pair of Top 20 hits in 2014, "If I Go" and "Comeback." By the end of the year, Eyre had finished work on her debut full-length Feline, featuring an array of producers (Ilya, DJ Fresh, Sigma, Sigala). The album appeared in February 2015, peaking at number four in the British chart; soon after, the single "Together" became her third Top 20 hit in less than a year. ~ James Wilkinson
