Mel Wesson (born 12 February 1958) is a British film, TV and video game composer and ambient music designer. He is one of the most influential 'musical sound designers' in Hollywood, yet his sound is often hard to describe or even identify. He is probably best known for his tight collaboration and work with Hans Zimmer and has contributed with both ambient music design and music to some of last decades biggest Hollywood blockbusters. He has also made numerous production music CDs for Extreme Music which loosely feature some of the atmospheric textures in his world of ambient music design.

On the Inception premiere in Hollywood, Mel and Hans designed an out-door sound installation using the atmosphere and soundscapes from the movie itself, exclusively for the audience. In Mel's own words: "Hans wanted the audience to remain within the Inception dreamscape as they left the LA Inception Premiere. In order to achieve this I put together a 40 minute soundscape designed to surround the audience as they followed the mirrored walkway from the Gaumans Chinese Theatre in Hollywood to the nearby aftershow reception. The soundscape comprised of ambience from the movie, together with a few well chosen FX from Inception sound designer Richard King.
