The artistic potential of the multitrack recorder came to the attention of the public in the 1960s, when artists such as The Beatles and The Beach Boys began to multitrack extensively, and from then on virtually all popular music was recorded in this manner. The technology developed very rapidly during these years. At the start of their careers, the Beatles and Beach Boys each recorded live to mono, two-track (the Beatles), or three-track (the Beach Boys); by 1965 they used multitracking to create pop music of unprecedented complexity.
