William Otis Laswell (born February 12, 1955) is an American bass guitarist, record producer, and record label owner. He has been involved in hundreds of recordings with many collaborators from all over the world. His music draws from funk, world music, jazz, dub and ambient styles. He has played or produced hardcore punk and heavy metal. According to music critic Chris Brazier, "Laswell's pet concept is 'collision music' which involves bringing together musicians from wildly divergent but complementary spheres and seeing what comes out."
