William Otis Laswell (born February 12, 1955) is an American bass guitarist, record producer, and record label owner. He has been involved in thousands of recordings with many collaborators from all over the world. His music draws from funk, world music, jazz, dub and ambient styles. 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." The credo of one record label run by Laswell which typifies much of his work is "Nothing Is True, Everything Is Permitted".
