William Otis Laswell 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.

Dub is an electronic musical style that grew out of reggae in the late 1960s and early 1970s. It is commonly considered a subgenre of reggae, though it has developed to extend beyond that style. Generally, dub consists of remixes of existing recordings created by significantly manipulating the original, usually through the removal of vocal parts, emphasis of the rhythm section, the application of studio effects such as echo and reverb, and the occasional dubbing of vocal or instrumental snippets from the original version or other works.
