Adrian Smith, English guitarist and songwriter
Adrian Frederick "H" Smith (born 27 February 1957) is an English guitarist, best known as a member of British heavy metal band Iron Maiden, for whom he writes songs and performs live backing vocals on some tracks.

Smith grew up in London and became interested in rock music at 15. He soon formed a friendship with future Iron Maiden guitarist Dave Murray, who inspired him to take up the guitar. After leaving school at 16, he formed a band called Urchin, which he led until their demise in 1980. He joined Iron Maiden in November 1980, replacing Dennis Stratton. Following a short-lived solo project called ASAP, he left Iron Maiden in 1990 and, after a year-long hiatus, formed the band The Untouchables, which later became Psycho Motel. In 1997, Psycho Motel was put on hold when Smith joined the band of former Iron Maiden singer Bruce Dickinson. Smith and Dickinson would both return to Iron Maiden in 1999, after which the band gained new success. During his second tenure with Iron Maiden, Smith has also led the side projects Primal Rock Rebellion and Smith/Kotzen.
