David Scott Lucas, born May 10, 1970, is best known for being the singer and guitar/bass player, as well as the only remaining original member, of the grunge band Local H.

Local H was formed in Zion, IL by high school friends Lucas, bassist Matt Garcia and drummer Joe Daniels in 1987. The band originally had as many as five members, but members would leave and rather than replacing them, the band just went on with the same musicians. The band was down to three members, Lucas, Garcia and Daniels, and then Garcia left, leaving just two members. They initially searched for another bass player but couldn't find what they were looking for. So, Lucas decided to add bass pickups to his guitar so that he can essentially play guitar and bass at the same time. In 1999, Daniels then left the band, who was replaced by Brian St. Clair, which made Lucas the only remaining original member of the band.
