The Wave is the debut solo album from the former Keane frontman Tom Chaplin. Chaplin has called the process of recording a solo album a "daunting prospect for someone who knows nothing else." Following the band's split, Chaplin began using drugs due to anxiety over the album and "thought [he] was going to die" in early 2015: "When I finally liberated myself from years of spiralling addiction, a place of inspiration and creativity became available to me. I set about writing an album that documents my transition from the darkest recesses of human experience to a place of resolution, fulfillment and happiness. At long last I am comfortable in my own skin and have achieved that elusive dream of writing a set of songs I can truly call my own."
