In April 2013, it was announced that Sykes would have to undergo emergency throat surgery in Los Angeles, California, and the band decided to go on hiatus while he recovered. The timing proved to be unfortunate, as the recording of their third album and a worldwide tour were about to start. After a lengthy period of recuperation, Sykes returned with his fellow bandmates with an emotionally charged performance at the Capital FM Summertime Ball in June 2013. With his vocal ability back on track, he collaborated with singer Ariana Grande on the duet "Almost Is Never Enough," which was featured on the soundtrack to The Mortal Instruments: City of Bones. It was widely praised by his musical peers and marked a triumphant return for the singer after a difficult year. Following the 2014 announcement that the Wanted were breaking up, Sykes signed a recording contract with Global Radio. In early 2015, he released the solo single "More Than You'll Ever Know" and announced that he was working on a debut full-length album with a handful of producers, including Babyface and Diane Warren. His second solo single, "Kiss Me Quick," followed in June 2015. Following a handful of singles, Sykes finally released his debut album, Unfinished Business, in November 2016. ~ Aneet Nijjar, Rovi
