Humberto Gessinger (born December 24, 1963) is best known as the singer, guitarist, and bassist from the Brazilian band Engenheiros do Hawaii.
In late 1984, Gessinger formed a rock band besides two friends from architecture college at UFRGS, Carlos Maltz and Marcelo Pitz, to play in a parade made by students. The band decided to call themselves Engenheiros do Hawaii , as a joke with the surf wear that most engineering students sported at the university campus - far away from the nearest beaches.
The band released their first album in 1986, although they had already appeared in a "promising bands" collection of BMG Music in 1985. With the departure of Marcelo Pitz in May 1987, Gessinger started playing bass and the band recruited Augusto Licks as lead guitarist, becoming one of the most successful bands at the time. After the departure of both Licks (1993) and Maltz (1996), it entered a brief hiatus while Gessinger played along his newly formed band, Humberto Gessinger Trio. Engenheiros do Hawaii reunited in 1997 with the trio's formation (Humberto playing bass, Luciano Granja on guitar and Adal Fonseca on drums). In 2001, with yet another new formation of the band (Paulinho Galvão on guitar, Bernardo Fonseca on bass and Gláucio Ayala on drums), Gessinger returned to lead guitar.
