The son of Nigerian and Brazilian parents, Seal was raised in England. After graduating with an architectural degree, he took various jobs around London, including electrical engineering and designing leather clothing. After a while, he began singing in local clubs and bars. He joined an English funk band called Push, touring Japan with the band in the mid-'80s. When he was in Asia, he joined a Thailand-based blues band. After a short time with that group, he traveled throughout India on his own.
Upon returning to England, Seal met Adamski, a house and techno producer who had yet to make much of an impression within the U.K. Seal provided the lyrics and vocals for Adamski's "Killer," which became a number one hit in 1990. After "Killer" became a hit, Seal signed a solo record contract. He recorded his eponymous debut album with Trevor Horn, who had previously worked with ABC, Frankie Goes to Hollywood, and the Buggles. The first single pulled from the album, "Crazy," became a number 15 hit in the U.K. and reached number seven in America upon its release in 1991. Seal was also a success, reaching number 24 in America and selling over three million copies around the world.
