William John Paul Gallagher is an English singer and songwriter. He achieved fame as the lead vocalist of the rock band Oasis from 1991 to 2009, and later fronted the rock band Beady Eye from 2009 to 2014, before starting a successful solo career in 2017. Oasis had various line-up changes, though Gallagher and his older brother Noel remained the only staple members. One of the most recognisable figures in British rock music, Gallagher is noted for his distinctive vocal style and outspoken, arrogant, and volatile personality. His demeanour during Oasis' commercial peak in the mid-1990s garnered much attention from British tabloids, which often ran stories concerning his drug use and self-destructive behaviour. Gallagher was interested in joining a band called the Rain, which they agreed to rename. It became Oasis, and they invited Noel to join them as the lead guitarist. The band's debut album, Definitely Maybe, was a critical and commercial success.
