Final answer:
Les Paul first invented multi-track recording on analog audio tape in the 1940s, which revolutionized music production and influenced other forms of media such as video art.
Step-by-step explanation:
The person who first invented multi-track recording on analog audio tape was Les Paul. In the late 1940s, Paul developed a prototype called 'The Octopus' using discarded movie sound equipment. This led to the first eight-track recorder, built by Ampex on Paul's commission, in 1955. Les Paul's invention of multi-track recording revolutionized how music was recorded and produced, allowing individual parts of a recording to be captured and manipulated separately.
The impact of multi-track recording technology extended beyond music. It helped in shaping new media, such as video art, which also utilized advancements in recording technology. Video art artists like Nam June Paik and Christian Marclay used recording mediums to blend sound and visual arts, similar to how Les Paul blended individual sounds to create complex musical recordings.
