David King is an American drummer from Minneapolis. He is known for being a founding member of the jazz groups The Bad Plus and Happy Apple. King is also active in many other projects including free jazz collective Buffalo Collision with NYC "downtown" musicians Tim Berne and Hank Roberts and the electronic art/pop group Halloween, Alaska. He is also a member of the noise/prog band The Gang Font with former Hüsker Dü bassist Greg Norton. He also has a jazz quintet called Dave King Trucking Company.

Suspicious Activity? is the fourth studio album by the American jazz band The Bad Plus. The band had previously garnered attention for covering well-known rock songs in an "acoustic power trio" style, but Suspicious Activity? includes only one cover version: the theme to the 1981 movie Chariots of Fire. Instead, the album focuses on the band's original music, including the track "O.G. ," which is a tribute to the legendary jazz drummer Elvin Jones.
